This laser driver, ATLS10A217, 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, 0.2V_VPS ~ 0.8V_VPS,  allows driving one or multiple serial laser diodes at the same  time, for up to 10A well controlled current at high efficiency.  The extremely low noise between DC ~ 5kHz 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. Heat sink is  necessary for normal operation.

The fully shielded case blocks all the incoming and  outgoing EMIs (Electro-Magnet Interferences). Therefore, this laser will not interfere other surrounding electronics, nor will be interfered by them.  The  small package saves valuable PCB space in laser systems.
