A multipass laser system is proposed for extending the period over which Thomson scattering measurements can be made with tokamaks. A Pockels cell and polarizer are used to reroute the pulse, which is reflected back through the plasma, away from the main amplifier, and onto a mirror, thus forming a closed system. A number of lenses and apertures are included in the system to maintain beam quality, with low gain amplifiers being used to maintain pulse energy.
提出了一种多程激光系统，用于延长托卡马克装置进行汤姆逊散射测量的时间周期。使用普克尔盒和偏振器来重新引导脉冲，该脉冲被反射回穿过等离子体，远离主放大器，并照射到镜子上，从而形成一个封闭系统。系统中包含多个透镜和孔径以保持光束质量，同时使用低增益放大器来维持脉冲能量。
