Analysis of Raman and thermal effects in kilowatt fiber lasers
Abstract
A theoretical analysis of Raman and thermal effects in kilowatt ytterbium-doped double-clad (YDDC) fiber lasers is presented. Solutions to suppress these detrimental effects in the YDDC fiber lasers under bidirectional end pump and distributed pump are discussed. The quantitative analysis shows that the Raman effects can be suppressed by using large-mode-area fibers, shortening the cavity length, adopting a longer lasing wavelength, and …
