摘要：
本文提出一种基于高掺杂硒化铬锌（Cr:ZnSe）晶体的放大器，用于提升电子束团穿过波荡器磁体后发射的脉冲能量。其核心动因是可利用粒子加速器储存环中循环束流发射的经放大波荡器辐射，来提高粒子束的相空间密度——该技术被称为光学随机冷却（OSC）。本文采用简单四能级模型估算Cr:ZnSe的单程增益，并结合数值计算与波荡器辐射的波动光学模拟，估算放大后波荡器波包的预期特性。
英文摘要：
An amplifier based on a highly-doped Chromium Zinc-Selenide (Cr:ZnSe) crystal is proposed to increase the pulse energy emitted by an electron bunch after it passes through an undulator magnet. The primary motivation is a possible use of the amplified undulator radiation emitted by a beam circulating in a particle accelerator storage ring to increase the particle beam's phase-space density---a technique dubbed Optical Stochastic Cooling (OSC). This paper uses a simple four energy level model to estimate the single-pass gain of Cr:ZnSe and presents numerical calculations combined with wave-optics simulations of undulator radiation to estimate the expected properties of the amplified undulator wave-packet.
