摘　　要：采用溶胶-凝胶(sol-gel)和聚合物聚甲基丙烯酸甲酯(PMMA)为基质,Pyrromethene-567(PM567)为增益介质,调Q倍频Nd:YAG激光为抽运源,实现了宽带固体染料脉冲激光输出。溶胶-凝胶基质和聚合物基质输出谱线中心分别为560nm和561nm,半峰全宽(FWHM)分别为9nm和8nm;采用透过率为50%的输出镜,激光斜率效率分别为43%和26.3%,最高输出能量分别为13mJ和99mJ。In this paper, solid-state dye lasers of sol-gel host and polymethyl metaerylate （PMMA） host were both prepared, pyrromethene-567 （PM567） was used as laser gain media, and the second harmonic generation （SHG） of Q-switched Nd： YAG laser （532 nm, 20 ns） was used as a pumping source. In sol-gel host, peak wavelength of output laser spectrum was 560 nm, and full width at half maximum （FWHM） of the bandwidth was 9 nm. In polymer host, peak wavelength of output laser spectrum was 561 nm, and the FWHM was 8 nm. The relation of output energy versus input energy was also studied. For the sol-gel and the PMMA host solid-state PM567 lasers, respectively, the slope efficiencies were 43% and 26.3%, and the highest energy outputs in the experiment were 13 mJ and 99 mJ.
