633nm Narrow-band Laser

633nm Narrow-band Laser


ATR20202-633 narrow line laser is characteristic by its high reliability and ultra-narrow line-width. ATR20202-633 operates with a single 5V power supply and can output 300 mW laser power. When ATR20202-633 is used in Raman spectrometer, it will help to obtain high spectral stability and high resolution. It can be controlled through the TTL interface by the offered pin-out definition and the communication protocol. The output laser power can be changed continuously by changing the LD working current with the commands.
