摘要

以改性聚甲基丙烯酸甲酯(MPMMA)、芘567 (PM567)和香豆素460 (C460)共掺杂为基料制备固态染料样品。研究了C460浓度对固态染料介质激光性能的影响，包括光谱特性、激光斜率效率和光稳定性。在PM567:C460=2:10的样品中，激光斜率效率最高，达到66.66%。当脉冲能量高达100 mJ (0.26 J/cm2)，以5 Hz的重复频率泵送样品时，样品中大约有398000个脉冲(PM567:C460=2:2)，激光输出能量下降到初始值的一半。我们的研究结果表明，在高脉冲能量泵浦下，MPMMA与PM567和C460共掺杂可以获得高效率、长寿命的固态染料激光器。

Highly photostable solid-state dye lasers based on MPMMA co-doped with PM567 and C460

Solid-state dye samples based on modified polymethyl methacrylate with methanol (MPMMA) co-doped with pyrromethene 567 (PM567) and coumarin 460 (C460) were prepared. The effects of C460 concentration on the laser performances of the solid-state dye mediums, including spectra property, laser slope efficiency and photostability were studied. The highest laser slope efficiency of 66.66% was obtained in the sample (PM567:C460=2:10). When the samples were pumped at a repetition rate of 5 Hz with a pulse energy as high as 100 mJ (the fluence was 0.26 J/cm2), the laser output energy dropped to half of the initial value after approximate 398000 pulses in the sample (PM567:C460=2:2). Our results have shown that it can obtain a high-efficiency and long-lifetime solid-state dye laser under high pulse energy pump using MPMMA co-doped with PM567 and C460.
