High power raman fiber laser
WebOct 5, 2024 · Another way to obtain high-power laser output is the Raman fiber laser (RFL), which employs the stimulated Raman scattering (SRS) effect in a piece of passive fiber without any rare-earth dopants [6–8]. Compared with Yb-doped fiber lasers (YDFLs), the most attractive feature of the RFL is wavelength flexibility. WebJan 8, 2024 · The cascaded Raman fiber laser is a proven technology that provides wavelength agile high-power fiber lasers outside the rare-earth emission windows. However, conventional cascaded Raman fiber lasers lack wavelength agility due to the use of fixed wavelength fiber Bragg gratings. Recently, proposed cascaded Raman fiber lasers based …
