摘要:A 1103-nm BaWO4Raman laser is demonstrated with a 1064 nm pump laser. A 5 mm × 5 mm × 46 mm BaWO4crystal with scattering geometry X(ZZ)X¯ configuration is employed as the active medium and its 332 cm-1Raman mode is accomplished. At an incident pump power of 7.55 W, the first-Stokes power of 1.23 W at 1103.2 nm is obtained at a repetition rate of 17 kHz, corresponding to an optical-to-optical conversion efficiency of 16.3%. The pulse width of Raman laser is measured to be 27 ns and the peak power is 2.6 kW. The beam quality factors M2in the two orthogonal directions are 2.0 ± 0.2 and 1.8 ± 0.2, respectively. The thermal focal length of the BaWO4crystal is estimated to be -1100 mm under this condition.
