Abstract
- Abstract: Based on the principle of spectral beam combining using a transmitting volume Bragg grating, a simple experimental setup was designed, in which an approach to control the incidence angles of beams using a focusing lens is presented. The experimental results for the spectral beam combining of two fiber lasers are reported. The gain media used in this experiment were large-mode area Er3+/Yb3+ co-doped double-clad fibers, pumped by semiconductor lasers. The output powers of the two fiber lasers were 0.39 and 0.53W, respectively. With a grating diffraction efficiency of about 60%, a maximum combined power of 0.64W with an absolute combining efficiency of about 69.6% was achieved. [Copyright &y& Elsevier]
