633nm,830nm,1064nm narrowband laser features embedded fiber can protect fiber well from breaking, high reliability, and narrow band width. ATR20203 operates at a single 5V power supply, and outputs a 600 mW laser power. When laser works for Raman spectrometer, it's used to obtain high spectral stability and high resolution as a result. Being controlled through the TTL interface of pin-out and the communication protocol. Laser output power can be changed continuously by changing the LD working current with the command.
