Quasi-Continuous-Wave Semiconductor Laser Power Supply STJ-QCW50150
This series of quasi-continuous-wave semiconductor laser power supplies is designed to drive QCW semiconductor laser devices and is also called a quasi-continuous laser diode array driver. Modern power-electronic components, high-speed microprocessor (MPU) program control and low-power linear pulse modulation provide excellent voltage/current output. The pulse-current waveform approaches an ideal rectangle without overshoot, kickback or surges, with good rising and falling edges and very low switching interference and output noise. Comprehensive multiple protections reliably protect semiconductor laser devices. Pulse parameters can be adjusted locally or by computer, selected through software. An adjustable delayed synchronization output supports synchronized multiple-unit or Q-switched operation. A resettable pulse counter PC counts over 400 million output pulses, and an alarm-control input, such as a water-pressure alarm, stops the supply for protection. The interface uses a 240*128 dot-matrix graphic LCD or a 16-digit figure-8 digital display, simple menus and membrane keys, with a friendly interface and fault diagnostics. The well-equipped, stable, powerful and cost-effective unit is advanced among comparable domestic and international products and well suited to integration by laser-equipment manufacturers. An optional semiconductor/TEC cooling supply, with complete PID software, intelligent continuous temperature adjustment and heating/cooling, forms a constant-temperature cooling system for better laser performance and smaller equipment. Its temperature parameters can be set independently or centrally through the QCW supply LCD interface, using a serial cable to the laser supply. Note 1: notify the company when ordering if 110VAC mains power is required. Note 2: 4 chassis choices: W×L×H＝304×295×88mm (Y1, S1); W×L×H＝425×310×88mm (Y2, S2). Note 3: table data describe standard supplies; products can be customized. Note 4: an adjustable pre-current, also called preheating, holding or base current, is available on request.
