Mid-infrared single-frequency fiber laser

Short Description:

Erbium group develop the all-fiber single-pass differential frequency laser (FA-SDFG) extend the wavelength to Mid-infrared range. FA-SDFG series use ultra-narrow linewidth DFB as the seed source. All-fiber amplifier amplify the laser power. The periodic polarization crystal is adopted for producing the high power differential frequency laser. The wavelength range of the FA-SDFG series cover 2.4-4.0 um. The laser has the characterizers of narrow laser line width (Lorentz linewidth <10kHz), no mode jump under a large range of temperature and vibration conditions, excellent laser beam quality (M² <1.2), high output power and low intensity noise.
