This laser driver, ATLS4A217, 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 700kHz), wide modulation bandwidth, and
small size. The wide output voltage range, 2.8V ~ 22V,
allows driving one or multiple serial laser diodes at the same
time, for up to 4A 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.
