反应堆抽运Xe激光多折腔研究

Study on a Folded Resonator for Reactor-pumped Xenon Lasers

针对反应堆抽运激光(RPL),介绍了一类具有多折光路、与反应堆有较高耦合效率的谐振腔。在俘获放能介质于腔内均匀分布的情况下,给出了激光器的匹配设计要素和裂变反应能在腔内的沉积,提供了该腔型耦合优化的模拟方法,为较大规模的RPL实验提供了理论依据。

A kind of flat box-like resonator for reactor-pumped lasers (RPL) is presented here, which has a zigzag propagation inside and high coupling efficiency with the reactor. Under the condition of uniform energy loading in the cavity, several factors of laser design and parameters relating energy deposition are explored. A method for optimizing output coupling is reported as well. These will benefit future experimental work.
