QCW Laser Diode Drivers With High-speed Microprocessor Program Control Technology
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.
