摘　　要：为了明晰碟片多通放大器的腔体设计方法,本文对不同类型的碟片多通放大器做归纳与总结,共归纳出4f中继成像、谐振腔设计/光学傅立叶变换、近准直光束传输与其他共4种设计理念的多通放大器。介绍了每种放大器的设计方法并详尽列举了研究现状。通过对比4种类型的碟片多通放大器,发现不同种类的多通放大器各有优缺点。4f中继成像需要真空环境以避免焦点处的气体电离,因此机械装置与调试难度较大;谐振腔设计/光学傅立叶变换概念多通放大器的镜片处存在较小光斑,因此较适用于较低能量的多通放大器;近准直光束传输方法由于不需要真空环境,具备很大的发展潜力,但需要精准控制激光运转状态下的碟片面形,难度也较大。因此,从激光器设计角度来看,需要对碟片多通放大器继续进行优化设计,从而同时实现使用场景的多元化与输出能量的可持续拓展。In order to clarify the cavity design methods of thin-disk multi-pass amplifiers,we summarize the different types of thin-disk multi-pass amplifiers and concludes that there are four fundamental design concepts:(1)4f relay imaging,(2)resonant cavity design/optical Fourier transform,(3)near-collimated beam transmission,and(4)others.Each amplifier design method is described and the current status of its research is listed in as much detail as possible.By comparing the four types of disk multi-pass amplifiers,it is found that the varying methods have distinct advantages and disadvantages.4f relay imaging requires a vacuum environment to avoid gas ionization at the focal point,making the mechanics and adjustment more difficult;the resonant cavity design/optical Fourier transform concept multi-pass amplifier has a small spot at the mirrors,making it more suitable for lower energy multi-pass amplifiers;the near collimated beam transmission method has great development potential because it does not require a vacuum environ-ment,but accurately controlling the surface shape of the thin-disk is difficult while the laser is operating.Therefore,from the perspective of laser design,it is necessary to continue to optimize the design of the thin-disk multi-pass amplifier to realize the diversification of application scenarios and the sustainable expansion of output energy.
