窄带、高光谱纯度、高效率染料激光器振荡-放大系统
A narrow bandwidth,high spectral purity and high efficiency dye laser oscillator-amplifier system
【摘要】 <正>欲在振荡器获得较大的峰功率(或能量),则腔内损耗元件(如F-P标准具等等)不能过多;而要使激光线宽变窄,则因增加腔内损耗元件而加大腔内损耗.即欲从振荡器里同时获得高峰功率(或能量)和窄线宽是相互矛盾的.解决此问题有两个途径:一是采用增加放大级的方法;二是采用注入锁定技术的方法.我们采用前一种方法.参考文献[1],研制了染料激光器振荡-预放大系统以及染料激光器振荡-预放大-放大系统,用XeCl准分子激光作为泵浦源,对它们的参数与性能分别进行了测试和讨论.
【Abstract】 A dye laser oscillator-amplifier system with narrow bandwidth, high spectral purity and high efficiency was developed. A linewidth of 700 MHz (single longitudinal mode) has been obtained at A=600 nm. The conversion efficiency is 13%, and S/N ratio is 0.25% (at =591 nm). Conversion efficiency of up to 15% has been obtained.
