1.1 Distributed Feedback Single Frequency Fiber Laser

Low-Linewidth, Low-Noise, No Mode-Hopping, Wavelength Tunable, Linear-Polarization

Single-frequency fiber laser has the greatest advantage of high-purity single-frequency laser outputting with narrow-linewidth. Single-frequency fiber laser offered by us uses the technology of distributed feedback to generate linearly polarized single frequency laser in an all-fiber structure. The single-frequency operation is stable and efficient by adopting unique side frequency suppression technology. A special assembly structure is also used to isolate the impact of external environmental vibration and temperature changes, thereby effectively improving the long-term stability on frequency and narrowing the linewidth. Also in this way, the laser mode will never be hopped. At present, the average output power is greater than 10 mW, 40 mW and 10 mW at the band of 1 μm, 1.5 μm and 2 μm, respectively. The output wavelength is flexible and the linewidth is always less than 20 kHz. The wavelength thermal tuning range is as high as 0.8 nm and the fast frequency tuning range can reach 3-5 GHz. The laser also has good power stability (RMS<0.5% @3 hrs) and excellent beam quality (M2 <1.05). Therefore, the single frequency fiber laser offered by us is the best choice for cold atom physics, high power laser system, sensing and lidar applications.

Narrow-linewidth continuous-wave (CW) lasers at visible or ultraviolet (UV) wavelengths have various important applications in the fields of atomic and molecular physics, measurement, communication, biology, etc. In the quantum simulation experiment, high-power 532nm lasers with ultra-low frequency noise can be operated as optical lattice trap, providing enough trap depth for ultra-cold atoms and improving the signal-to-noise ratio of atoms. Besides the visible lasers, high-power CW ultraviolet lasers have been widely needed in the experiments of laser cooling, clock frequency detection, ionization, etc. For example, the long-range interaction of Rydberg atoms has a great advantage in quantum information, Rb can be excited to Rydberg state by single-photon process with 297 nm.

Center frequency drift of 0℃ -50℃ is about 340 MHz, and the center frequency drift of 25℃ for 2 hours is about 40 MHz

The experiment of high and low temperature impact storage at -30℃ -70℃ showed that the laser normal operation after high and low temperature shock.

RMS power stability under high and low temperature impact

When the ambient temperature changes from 0℃ -50℃ at interval of 10 ℃. Although the laser power will jump during the temperature change process the power will remain stable at each temperature.

The stability of the first channel at each temperature point in the high-low temperature test was measured. The power stability of the 2-hour RMS at the limiting temperature of 0℃ and 50℃ was better than 0.2%. The power stability of the second channel is also better than 0.2% (single temperature point, RMS)

Frequency tuning test

The seed has a reserved frequency sweep interface, and the 780nm laser frequency sweep range is about 3.2GHz.

Selecting a reasonable frequency locking point and controlling an appropriate frequency difference and frequency shift between the two channels, a dualchannels.780 nm laser can provide all the lasers required for the experiment of rubidium atomic gravimeter. The product has good environmental adaptability and is an excellent choice for laser source of transportable atomic gravimeter.

4.6 780nm laser frequency locking module

Cold atom experiments with Rb need lasers with specific frequency and we launch different frequency locking schedules for 780nm laser. We built up an all-fiber-connected frequency locking module with an integrated optical system and other optical fiber devices. This module can offer stable SAS or MTS signal and together with our laser controller, frequency locking with good long-term stability is realized. The frequency difference between two lasers should keep to a constant value in some cold atom experiments. For 87Rb atom gravimeter, the frequency difference of cooling laser and repumping laser should be about 6.6GHz and for the two Raman lasers the value is 6.834GHz. We have launched a specialized laser controller for offset frequency locking in the range from 50MHz to 8GHz with beat frequency/phase locking technique.

(1) Integrated optical module

With integrated spatial frequency-locking module, we build an all-fiber-connected frequency locking module. This module gives a stable SAS or MTS signal at Rb D2 line and the spectrum can offer error signal for frequency locking of 780nm laser

Dimensions of integrated frequency-locking optical module

SAS and MTS signal from the integrated optical module

(2) Multi-function laser controller

We offer a multi-function laser controller for frequency locking under different condition. The controller is integrated with modem, PID module and High-Voltage amplifier and it can work as error signal generator, PID servo and PZT driver at the same time. All functions are controlled by software with no physical button or knob. The controller can work in different mode under customized. Under internal-modulation mode laser is locked with SAS or AS while under external-modulation mode laser is locked with MTS or PDH technique.

Front panel of controller

(3) SAS-Locking

Frequency locking with SAS is based on Lock-in amplifier. Take the SAS of 85Rb atom as example, the controller get SAS signal from integrated optical module and generate error signal with lock-in amplifier, the PID module in the controller will then lock the frequency of 780nm laser.

SAS and error signal in our software

We build two independent SAS-locking system for 780nm Laser and take a laser beating test with their 1560nm seed laser. This can show the stability of frequency locking.

(4) MTS-Locking

Unlike SAS-locking, MTS-Locking is under extern-modulation mode and the spectrum signal getting from demodulation can directly serve as error signal. Also take the MTS of 85Rb atom as example, integrated optical module provide both SAS signal and modulated MTS signal to the controller. After demodulation, the MTS signal will be error signal for frequency locking while the SAS signal here will be a reference signal. Due to their different principles, locking point of MTS and SAS are not the same.

SAS (reference) signal and MTS (error) signal in our software

Take also the beating test with two independent MTS-locking module.

(5) Beat phase/frequency locking module

Beat phase/frequency locking module is used for frequency locking of multi-lasers. We has launched a frequency control system for dual-channel 780nm laser device which serves as the laser source of 87Rb gravimeter and gradiometer. Frequency of channel1 is locked to the resonance peak with MTS-locking while channel2 is locked 6.834GHz offset from channel1 with beat phase locking. This dual-channel laser can offer almost all the laser that is needed for a 87Rb gravimeter.

Error signal and output signal in our software

Beat phase/frequency locking is realized with our controller. A fast PD measures the beat signal between two lasers and the PFD module in our controller generates error signal with the beat signal and a reference signal, the laser frequency will then be locked by PID module.

The 3.4 GHz beat signal from two 1560nm lasers

For 87Rb atom gravimeter, frequency chirping or jumping of laser is needed. A typical example is the Raman lasers whose frequency need to change within 3 pulses to compensate the doppler effect. Our controller provides frequency jumping function with a switching time below 10 μs.

STG Series DFB Lasers & Modules

1. STG Series DFB Lasers

Distributed feedback (DFB) lasers provide tunable wavelength output with extremely narrow spectral width and long coherence length. Integrated modules offer further narrowing of the spectral line in a compact OEM package with a simple tuning interface.

DFB lasers feature a grating on the chip level structure to generate feedback into the cavity which ultimately enables stable, smooth, and precise wavelength tuning via temperature control of the chip. Additional feedback or external locking methods can ensure extremely stable wavelength control through many years or decades of use.

Our DFB lasers serve a wide range of industrial, defense, medical, and scientific applications, with performance-enhancing design features that include:

Integrated thermoelectric coolers (TECs) to reduce current consumption and extend operating temperature range
Precision thermistors for accurate feedback and control of chip temperature
Internal isolators to protect against back reflections and to reduce noise perturbations into the laser
DFB Lasers in 14-pin or 7-pin package

DFB lasers provide precise single-frequency and single-spatial-mode performance with smooth tuning capability via temperature or current (chirp) tuning. We offer a range of products with high power and high bandwidth options in a rugged, single-emitter, fiber coupled 14-pin or 7-pin butterfly package. Our high power series offers options up to 100 mW with >2.5 GHz direct modulation speeds, while our high bandwidth series offers up to 18 mW with >12 GHz direct modulation speeds. In addition to the variety of standard wavelength options in the 1-1.62 mm region, additional custom options are available upon request.

Applications cover distributed temperature sensing (DTS), fiber optic telecmmunications, gas sensing, interferometry, laser Doppler vibrometry (LDV), LIDAR, RF over fiber, seed lasers, spectroscopy.

2. STG Series DFB Laser Modules

Building upon our proven 14-pin packaged DFB lasers, we also offers compact OEM modules with excellent linewidth performance. All the modules comprise an integrated DFB laser, low noise diode driver, and TEC controller. To operate, the user need only provide a simple 5V power supply and voltage based tuning signals for temperature or current (chirp) adjustment, if required.

The incorporation of an ultra-low noise current source for the diode offers a vastly improved linewidth. The EM650 typically provides 200 kHz linewidth in a hand-sized package, roughly 66x64 mm (2.5”x2.5”) in size. The EM750 features an additional external cavity to reduce the linewidth to approximately 10 kHz while emitting up to 50 mW out of the fiber.

3. STG Series DFB Laser Modules

Our high power diode lasers feature ruggedized, epoxy-free designs intended for use in a wide range of harsh, long-life environments. Cooled and uncooled options are available to meet the most demanding diode laser applications.

Single-mode (SM) pump lasers emit a low noise, precisely controlled, polarization maintained level of light at a specific wavelength out of a small-core fiber. STG series of cooled and uncooled diode laser products are designed with precise micro-alignment that stays true and stable through wide temperature ranges and high shock/vibration environments. All SM lasers feature a fiber Bragg grating (FBG) for stable, low noise operation. Customers may select to use the laser without the grating to enable temperature tuning of the central wavelength.

The latest series of AC1409 SM lasers feature high PER performance, enabling superior PM pump combining and other polarization extinction ratio (PER) sensitive applications. In addition to standard products, output wavelength and other options can be customized for new applications.

Multi-mode (MM) lasers offer high output power. We offer standard 14-pin fiber-coupled package designs and other formats upon request. Cooled designs allow for wavelength tuning of the output for even greater wavelength control of the laser, while uncooled options feature higher power output.

Our lasers are designed to ensure highly reliable operation across wide temperature and environmental conditions. A variety of low size, weight, and power custom designs can be employed to meet demanding aerospace and space mission applications. We also offer design and qualification services to ensure high reliability and long life under launch conditions for space mission applications.

Applications cover fiber lasers, fiber optic, gyroscopes. Inspection, infrared sensing, life science, marking.

SFQCW-266nm Series CW Single-frequency DPSS Lasers

The DPSS CW deep UV laser series SFQCW-266, diode pumped continuous wave solid state laser, comes with a resonant frequency conversion stage, emitting a fixed wavelength of 266nm. The laser head is contained in a sealed aluminium housing, which allows operation in a wide range of environmental conditions. Heat removal from the laser head is done by air convection.

The SFQCW-266 plug & play laser comes with a control unit, allowing either push button control or remote control operation via serial (RS232 & USB) interface. The lasers offer excellent beam quality with an M2 below 1.3 , beam divergence below 0.8mrad (full angle), low intensity noise below 0.5% rms (100 kHz-10MHz) and a good power stability (<1% in 8 hours). These CW laser units are the proper tools for industrial use and intensive R&D applications as Raman Spectroscopy, Wafer inspection and Photoluminescence where a long coherence length is required.
