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。
Pyrromethene-567 (PM567) was used as gain medium and Q-switched Nd: YAG laser as pumping source, using sol-gel and PMMA as substrates. Broadband solid dye pulsed laser output. The output spectral centers of the sol-gel matrix and the polymer matrix are 560 nm and 561 nm, respectively, and the full width at half maximum (FWHM) is 9 nm and 8 nm, respectively. The output slope of the laser with the transmittance of 50% is 43% And 26.3%, the maximum output energy were 13mJ and 99mJ.
