Model ATLS500MA212 - 14V 500MA Laser Driver
From Laser Controllers/Drivers
This laser driver, ATLS500MA212, is an electronic module that has all the valuable and important, but often difficult to achieve simultaneously, features simultaneously: wide input and output voltage range, high output current capability, high efficiency, low output noise (but it has an output 4mVp-p ripple voltage at 500kHZ), wide modulation bandwidth, and small size. The wide output voltage range, 0 ~ 15V, allows driving one or multiple serial laser diodes at the same time, for up to 500mA well controlled current at high efficiency. The extremely low noise between DC ~ 10kHZ and low DC current drift make it ideal for driving diode pumped single mode laser diodes to achieve mode-hop-free and narrow optical wavelength drift, thus, long coherent length.
