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.

STU Series Single Frequency DPSS Lasers (NIR-UV)

• Leading edge research

• Any wavelength from NIR to UV

• Up to ten times higher conversion efficiency

• Excellent beam quality with M2 <1.05

Brief Description:

We are the only company, whose continuous wave single frequency DPSS lasers uniquely perform at any wavelength within the range from NIR to UV from just a single technology platform, using our proprietary patented Bragg Range Michelson Mode Selector (BRaMMS) DPSS laser technology. Whereas conventional light can be dispersed by a prism into a spectrum  of constituent colours, our lasers emit just one ultra pure colour.

Any wavelength from NIR to UV using a single engineering platform based on our proprietary patented BRaMMS DPSS laser technology, We develop and produce single frequency DPSS lasers for demanding applications in:

• Leading edge research

• Life sciences, BioMed

• Semicon

• Environmental metrology, etc

Using the BRaMMS laser technology we can offer any wavelength within spectrum range

• from IR (around 2µm) to through deep UV (<200nm)

• from our range of DPSS lasers operating in the CW single frequency regime. This is unique for a single platform laser technology.

All products feature laser cavity feedback locked single longitudinal mode CW performance with no lock loss and mode hops during 100s of hours of nonstop operation.

The excellent beam quality with M2 <1.05 emerges from the smallest footprint and at the lowest power consumption for given output, with noise figure as low as < 0.1%rms (10Hz-10MHz).

Benefits of our laser design include:

• Up to ten times higher conversion efficiency

• Power scalability without water cooling

• No mode beating & associated high frequency noise, which often limits applicability

• The longest coherence length of over 100m, effectively the path difference over which lasers can interfere.

It utilises the spectrum discriminatory feature of a Michelson interferometer setup within a spectral range preselected by VBG (Volume Bragg Grating).  This suppresses all but one lasing longitudinal mode within a laser cavity.  Hence – Bragg Range Michelson Mode Selector (BRaMMS).

Due to significantly lower power consumption for any required output and the resulting simplified thermal management, the BRaMMS laser technology provides up to 10 times wider range of output power scalability from the smallest footprint.

We advance this technology via three main engineering lines:

• STU-Solo-XXXX/XXXX, covering spectrum range 700nm-2000nm by the generation at the fundamental wavelength;

• STU-Duetto-XXX/XXXX, covering spectrum range 350nm -780nm by an intracavity second harmonic generation;

• STU-Quartetto-XXX/XXXX, covering spectrum range 200nm – 380nm by an intracavity fourth harmonic generation.

Our laser technology is wordwide protected by:

• US 8,498,316 –  Intra-Cavity Second Harmonic Generation (SHG) Laser Device

• EPO 10173991 –  Intra-Cavity Second Harmonic Generation (SHG) Laser Device (pending)

Our technology is able to displace bulky and inefficient gas lasers like argon-ion or helium cadmium lasers, dinosaurs of the laser industry. Our Single Frequency DPSS lasers are compact, reliable and long life systems, in demand for many cutting edge research and industrial applications, for example:

• life sciences instrumentation,

• semiconductor wafer metrology,

• holographic imaging,

• particle trapping,

• wind turbine power generation,

• avionic technologies…

Using the BRaMMS laser technology we can offer any wavelength within the spectrum range from IR (around 2000nm) through deep UV (<200nm) from its range of DPSS lasers operating in the CW Single Frequency regime.

Additionally, due to the significantly lower power consumption for any required output and the resulting simplified thermal management, the BRaMMS laser technology provides up to a 10 times wider range of output power scalability from the smallest footprint. This opens up applications in portable and remotely controlled systems and devices which until our products were available have never before considered feasible.

The following products have been released for sale:

• STU-Solo – 1064/XXXX from 50mW to 3W output power at 1064nm SLM

• STU-Duetto – 532/XXXX from 50mW to 2W output power at 532nm SLM

BRaMMS-Customised  – We can deliver any wavelength and adjust the power accordingly. Let’s discuss your requirements and find the best solution. You can open the product specification details by clicking on the relevant data sheet on the right hand side.

Applications:

We are the only company to be able to configure Continuous Wave, Single Frequency Lasers to uniquely emit at any wavelength covering the spectral range from Near Infra-Red to Ultra-Violet from a single universal technology platform, using proprietary patented BRaMMS technology.

The potential applications range is vast:

• holographic art to large scale structural analysis;

• from pharmaceutical instrumentation to cutting edge particle trapping techniques;

• from semiconductor wafer micro-processing to wind turbine power generation and avionic technologies.

Our novel patented BRaMMS technology provides reliable, cost effective, compact all-solid-state and class leading solutions for both well established and currently unavailable, but demanded, wavelengths. This opens up applications in portable and remotely controlled systems and devices, which have been never before considered feasible.

The newest generation of ultra compact, air cooled all solid state products is a new choice on the current deep UV spectrum market and a strong competitor to the pulsed laser technologies traditionally offered by large excimer UV gas lasers and water cooled frequency tripled/quadrupled Nd:YAG systems.

Let’s look at our newer laser with wavelength of 515nm. This laser has a scalable output power up to several Watts, and is a compact, reliable and long life plug-and-play replacement for the bulky and inefficient argon-ion gas laser with the same green emission.

The new laser will feature optimised second harmonic generation of the diode pumped ytterbium doped YAG (Yb:YAG) laser at 1030nm using our novel patented BRaMMS technology.

Argon ion lasers have been around since the end of the 1960’s and found broad applications in areas such as holography, printing, digital imaging, non-destructive testing including semiconductor inspection, spectroscopy, optical pumping, confocal microscopy, flow cytometry, DNA sequencers, compact disc and DVD mastering, photomask direct imaging, printed circuit board direct imaging, and precision optics inspection. However, they suffer disadvantages of being bulky (high power versions are several meters long) and inefficient (a 1W single frequency green laser has an efficiency of 0.01% requiring a large 10kW power supply with commensurate water cooling).

Benefits of our laser design include up to several orders of magnitude higher conversion efficiency, giving them unique output power scalability while eliminating the need for water cooling, a lack of mode beating and associated high frequency noise which often limits applicability, and the longest coherence length, over 100m, effectively the path difference over which lasers can interfere.

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.
