本文报道了一种连续激光二极管泵浦的Nd：GdVO 4薄片激光器，在912 nm的4F 3/2→ 4 I9/2准三能级跃迁和1063 nm的4F 3/2→ 4 I11/2四能级跃迁同时获得双波长输出。在912 nm和1063 nm的输出功率分别为1.7 W和1.6 W，300 μm厚的Nd：GdVO 4晶体在26.8 W二极管泵浦功率下多程激发。LiB 3 O 5对456 nm的二次谐波产生在912 nm单波长工作时产生0.96 W，在912 nm/1063 nm双波长工作时产生0.73 W。
A continuous-wave, diode-pumped Nd:GdVO4thin disk laser with simultaneous dual-wavelength emission at the 912 nm4F3/2→4I9/2quasi-three-level transition and the 1063 nm4F3/2→4I11/2four-level transition is demonstrated and analyzed. Output powers of 1.7 W at 912 nm and of 1.6 W at 1063 nm were achieved simultaneously from a 0.3-at.%, 300-μm thick Nd:GdVO4crystal that was multi-pass excited with 26.8 W of available diode pump power. Second harmonic generation to 456 nm with LiB3O5yielded 0.96 W in 912 nm single-wavelength operation and 0.73 W in 912 nm/1063 nm dual-wavelength operation.
