1695-2100nm Laser
Based on thulium-doped fiber (TDF) DFB seed lasers and amplification technology, it enables single-frequency laser output in the 1695-2100 nm range, with a maximum output power of 50 W. Meanwhile, it ensures extremely low intensity noise and phase noise of the output laser. This laser features high power, low-noise amplification, and ultra-fast seed cut-off protection, among other advantages.
Features

(1)X is the wavelength and Y is the output power, for 2W 1762nm laser, the partnumber is FL-SF-1762-2-CW.
(2) Seed laser has another rack in default, and can be put into the amplifier optionally.
(3) Beam size for collimated outout，If PM fiber FC/APC connector output，there is no extra collimator
Higher power, more wavelengths, customizable solutions
