IPG Photonics offers a family of linearly polarized single-mode CW near infrared Raman fiber lasers with output powers up to 70 W. Customer can select from several wavelengths in the range 1.1-1.25 microns. Based on IPG's efficient and reliable fiber laser technologies, these Raman Fiber lasers are offered as compact OEM modules. The all fiber construction allows for full range of output power adjustment without any change in power stability and beam mode parameters. The linearly polarized Raman fiber lasers feature narrow linewidth of ~0.1 nm. They are used for coherent beam combining, sensing/detection systems and other scientific and commercial applications.
