1.1 STO-LDa-gs Seed Laser / Picoseconds optical Pulser / Driver

The STO-LDa-gs seed laser assembly is an integrated solution for the seed (oscillator) part of pulsed MOPA fiber laser systems. The assembly includes all the key functions needed in a high-performance seeder, including a trigger generator, an adjustable pulse-width generator, laser driver, TEC controller and an integrated laser diode.laser diode driver

The optical peak power can be adjusted by an on-board potentiometer. The trigger source is selectable: internal or external. In external trigger mode each incoming trigger signal (rising edge) results in a generation of a single pulse.

The optical pulse-width is controlled by an external analog control voltage. The pulse-width range is from gain-switching mode (~50ps) to over 1ns. The module has also analog control inputs for bias current and set temperature. Each of the input analog control signals can be replaced by an on-board potentiometer so that the module can either be controlled externally or have internal settings. With the bias current-control the user can impact the optical spectral width or to change the extinction ratio.

The product is designed to operate in a wide temperature range and in maintenance-free conditions – making it a good choice for OEM integration in industrial laser systems. Various product options are being offered.

2. Transmitter modules for LIDAR: STO-LDb-5/10

The STO-LDb series modules were designed for systems requiring a short optical pulse source with high peak power. The modules operate in frequencies of DC up to 5MHz. The peak current is up to 25A and the optical peak power (at 905nm) is up to 75W – depending on the selected laser diode. In order to protect the laser diode, the average optical power is limited to 0.1W. The modules operate on a single 12V power supply and a trigger input signal in LVTTL or TTL levels (rising edge).

Optical pulse-width is programmable in two ranges:

The peak power is programable too.

Pulse-width and peak power programming is done either by on-board potentiometers or by external analog voltage controls. A monitor signal indicates the average laser current. The module was designed to be integrated in real-life systems that operate for years.

STJ Series QCW Laser Diode Drivers

The QCW Laser diode driver is specially designed for various QCW laser diodes at the compact size and modularization. It adopts the latest modern power electronic devices, high-speed microprocessor (MPU) program control technology, and low-power linear modulation technology (with extremely low ripple). It has excellent voltage and current output characteristics. No overshoot, no kickback, no surge and low noise when operation. It has perfect multiple protection functions, and has reliable protection for laser diode. The adjustment and control of current parameters can be selected by local and computer (setting by software). In addition, the driver also has alarm signal settings. (eg. water pressure alarm, for shutdown protection). The driver adopts 240x128 dot matrix graphic LCD or 16 bit "8" digital tube display, simple menu mode display, membrane button, and has friendly user interface and fault diagnosis function. And TEC for precision maintaining the temperature on peiltier element (TEM) is also an optional.

The QCW laser diode driver is an excellent choice for laser equipment manufactures and research institute. It can set the temperature parameters independently and you can also set the temperature on the LCD only via a serial line to connect to the laser driver.

Remarks:

LDDP Series Pulse Diode Drivers

LDDP series diode drivers are probably the most powerful diode drivers in the aesthetic world. Peak output power is up to 10kW (with user selectable IMAX and VMAX). Averaged output power is up to 1600W (assuming 100-240VAC input) and over 2000W on request (with 200-240VAC input).

Since the driver was especially designed for laser hair removal applications, it's fully compliant to the medical standards - IEC 60601-1 for electrical safety and IEC 60601-1-2 for electromagnetic compatibility. Besides, they are also widely used in diode pumping and direct diode laser applications.
