采用复合陶瓷材料设计了一种高脉冲能量、高平均功率的全反射有源镜（TRAM）放大器。一个啁啾脉冲再生放大器与低温TRAM已成功地证明作为一个可行性研究。在重复频率为100 Hz时获得了3.5mJ的脉冲能量。对于0.46ns的短脉冲，TRAM上相应的能量注量高达1.5J/cm ~ 2。M2因子低于1.1，并且没有观察到显著的光束失真。
A total-reflection active-mirror (TRAM) amplifier is functionally designed by using a composite ceramic for high pulse energy and high average power. A chirped-pulse regenerative amplifier with a cryogenic TRAM has been successfully demonstrated as a feasibility study. A 3.5mJ pulse energy is obtained at a repetition rate of 100Hz. The corresponding energy fluence on the TRAM is as high as 1.5J/cm2for 0.46ns short pulses. The M2-factor is below 1.1 and no significant beam distortion is observed.
