从Mogul电子公司可以买到激光功率放大器集成电路。由VTC研制的VM8001器件是一种高性能的集成电路,它可用于光学存储器件中的激光二极管驱动和功率监控。该器件可以将直流读电流和脉冲式写/抹电流提供给共阴极激光二极管,其上升和下降时间为4ns,过调量仅为3%。各管脚是分离的,从而将读输出与写输出和激光二极管绝缘。这些电流的电平分别由0V~5V范围内的模拟电压调节。
Laser power amplifier ICs are available from Mogul Electronics. The VM8001 device, developed by VTC, is a high performance integrated circuit that can be used for laser diode drive and power monitoring in optical memory devices. The device provides DC read current and pulsed write / wipe current to the common cathode laser diode with rise and fall times of 4ns and overshoot of only 3%. The pins are separated to insulate the read output from the write output and the laser diode. The levels of these currents are individually regulated by the analog voltage in the range of 0V to 5V.
