This laser driver, ALDD28V5A401, is an electronic module
that has all the valuable and important features, but are often
difficult to achieve simultaneously such as: wide input and
output voltage range, high output current capability, high
efficiency, low output noise (but it has an output 6mVp-p
ripple voltage at 500kHz), wide modulation bandwidth, and
small size. The wide output voltage range, 0.1VVPS ~
0.8VVPS, allows driving one or multiple serial laser diodes at
the same time, for up to 5A of 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.
