1940nm continuous fiber laser ( single-mode / polarization-maintaining 200W)
The Shanghai Hanyu 2.0um band (GHz) CW fiber laser series adopts a master oscillator power amplifier (MOPA) structure or a direct resonant cavity structure design, achieving high-power output. Pumping usually uses semiconductor or fiber lasers in the 793nm and 1570nm bands, with linearly polarized or randomly polarized output, suitable for device testing, medical, remote sensing, LiDAR, mid-infrared pumping and other application fields. Typical operating wavelengths are 1908nm, 1940nm, 1950nm, 2004nm, 2050nm, etc.
