| 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。

| Abstract: | In this paper,solid-state dye lasers of sol-gel host and polymethyl metacrylate(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. |
