A compact cascaded ultrashort cavity dye laser oscillator-amplifier

摘要: 本文报道新近研制的一个小型的两级短腔染料激光器(SCDL)串联加一级染料放大的装置。用大气压N2激光(λ=337.1nm)作泵浦源,与文献[1]报道的结构比较,系统紧凑简单,长宽不到20cm×15cm.采用较合理的光路,显着地减小N2激光光束的弥散损耗,使系统的效率有较大的提高。第二级SCDL腔的结构采用了不同于文献[1]的形式,有利于抑制其泵浦发热引起的热不稳定性。

Abstract: It is reported that a small oscillator-amplifier which consists of two cas-caded ultrashort cavity dye laser(SCDL)and a dye laser amplifier.The pumping source is an atmaspere pressure N2 laser(λ=337.1nm).The size of the system is less 20cm×15cm,compared with that described in[1],for a new optical geometry is employed.The beam diffusion loss of the N2 laser,used as the pumping source,is cut down greatly,therefore the system efficiency is raised obviously.The second SCDL cavity is constructed by using a new structure.So thermal unstability of the cavity and output features of the SCDL can be reduced.
