GENERAL DESCRIPTION

ATR20202 785nm narrow line laser is characteristic by its highreliability and ultra-narrow linewidth. ATR20202 operates with a single 5V power supply and can output 500 mW laser power.When ATR20202 is used in Ramanspectrometer, it will help to obtain high spectral stability and highresolution. It can be controlled through the TTL interface by the offered pinout definition and the communication protocol. The output laser power canbe changed continuously by changing the LD working current with the commands.
