ATLS1A103D can be used to drive laser diodes with low noise, including DPSSL, EDFA, SOA, fiber laser, direct diode lasers, etc.


The ATLS1A103 is an electronic module designed for driving diode lasers with up to 1A low noise current. When the maximum power consumed by the controller is maintained to <1W, it does not require a heat sink to operate. The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises. The output current of the ATLS1A103 can be set by an input voltage linearly or modulated by an external large signal of up to 1.2MHz in bandwidth, resulting in a minimum 1μS rise and fall times at the output current.
