Driving diode lasers with low noise, including DPSSLs, EDFAs, fiber lasers, diode laser modules, etc.
The ATLS1A102 is an electronic module designed for driving diode lasers with up to 1A low noise current. The output voltage is 1.5V to 4V when powered by a 5V power supply.
The ATLS1A102 has two input ports for modulating the output current: one for low speed of up to 0.08Hz bandwidth and the other high speed modulation of up to 300KHz. The former is for CW (Continuous Wave) operation and the latter is for modulated operation.
A high stability low noise 2.5V reference voltage is provided internally for setting the output current. This reference can also be as the voltage reference for external ADCs (Analog to Digital Converters) and DACs (Digital to Analog Converters), which might be used for monitoring and/or setting the laser current.
