High Voltage Constant Current Laser Driver ATLSxA218

For driving high voltage diode lasers or driving a serial of diode lasers simultaneously, we have developed ATLSxA218 series laser drivers/controllers. The input voltage can be between 5.5V to 15V, and the output voltage can be from 0.8V to 90% VPS, where VPS is the power supply input voltage. The maximum current capability is 15A. This laser driver is packed in DIP (Dual In Line) through hole package. We have also developed a load assembly that can be used to emulate the expensive laser diodes for evaluating the laser controllers, which is purposed to avoid making costly mistakes when evaluating this series of laser controllers.

ATLS15A218

This laser driver, ATLS15A218, features: wide input and output voltage range, high output current capability, high efficiency, low output noise (but it has an output 10mVp-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 15A well controlled current at high efficiency. The extremely low noise between DC ~ 10Hz and low DC current drift make it ideal for driving diode pumped laser diodes. Because of the high efficiency, the laser driver generates small amount of heat, thus, no heat sink is necessary for normal operation.
