摘　　要：介绍了一种无法拉第旋光器的驻波腔再生放大器,通过利用偏振片的剩余反射率,实现种子激光注入与再生腔输出激光输出的光路分离。最终,在10 kHz重复频率下,实现了平均功率为4.87 W的放大皮秒脉冲激光输出,对应的脉冲宽度为53 ps,激光光束质量因子为M^(2)<1.19。A standing-wave cavity regenerative amplifier without Faraday rotator is demonstrated. In addition, according to the residual reflectivity of the thin film polarizer, the beams of injected seed laser and output regenerative amplified laser are separated. Finally, under a repetition frequency of 10 kHz, an amplified picosecond pulse laser output with an average power of 4. 87 W is obtained, and the pulse width is 53 ps. Furthermore, the laser beam quality factor M^(2) is smaller than 1. 19.
