This laser driver, ALDD28V15A401, 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, wide modulation bandwidth, and small size.
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. Because of the high efficiency, the laser driver generates small amount of heat, thus, no 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.
