We demonstrate a tunable solid-state polymer dye laser with quasi-longitudinal pumping by two green ( λ = 513 nm) laser diodes. Tuning curves with a maximum efficiency of 13% were attained, using a plate of crystalline quartz (Lyot filter) for wavelength selection. In a three-mirror cavity with partial compensation of astigmatism, the total tuning range was 62 nm (from 545 nm to 607 nm) for pyrromethene dyes: PM567, PM580 and PM597. The best results were achieved with active elements based on Pyrromethene 580 laser dye in a mixture of polyvinyl butyral or a copolymer of butylmethacrylate and methacrylic acid (ratio 9:1) with the addition of 30% dibutylsebacinate as a plasticizer.

由两个513 nm二极管泵浦的可调谐聚合物染料激光

我们演示了由两个绿色（λ= 513 nm）激光二极管进行准纵向激励的可调谐固态聚合物染料激光器。使用一块石英板（Lyot滤光片）进行波长选择，可获得最大效率为13％的调谐曲线。在具有部分像散补偿的三镜腔中，吡咯亚甲基染料：PM567，PM580和PM597的总调谐范围为62 nm（从545 nm到607 nm）。在聚乙烯醇缩丁醛或甲基丙烯酸丁酯与甲基丙烯酸的共聚物（比例为9：1）的混合物中，加入30％的癸二酸二丁酯作为增塑剂，使用基于吡咯甲亚580激光染料的活性元素可获得最佳结果。
