Narrow linewidth Laser
Description
Narrow linewidth semiconductor laser is based on external cavity technology and mainly composed of gain chips, ALN substrate, etalon, lens, MPD, TEC, mirror, optical isolator and PM fiber in a hermetic package. DWDM Wavelength in C+L band can be customized. Operating temperature range is from -40℃ to 70℃. Optical output power is more than 10mW and the optical Lorentz linewidth is less than 2kHz. Optical wavelength no-hopping tuning range is up to ±50pm. Relative intensity noise is below -150dBc/Hz. It is widely used in free space optical communication, optical sensing ，Lidar, test and instrument，RF photonics.
