采用细棒Yb：YAG（钇铝石榴石）激光器结构，研制了一种高平均功率、激光二极管泵浦的皮秒脉冲再生放大器。这种结构具有一整套有利的性能，可用于高性价比、高平均功率和高峰值功率的激光器。这些包括具有高增益和高重复率的低放大自发辐射。对于放大器系统，在100 kHz的脉冲重复率下实现了20 W的平均输出功率，这对应于200 μJ的输出脉冲能量和2 ps的输出脉冲宽度。
A high-average-power, laser-diode-pumped, picosecond-pulse regenerative amplifier was developed using the thin-rod Yb: YAG (yttrium aluminum garnet) laser architecture. This architecture has a complete set of favorable properties for the cost-effective, high-average-power, and high-peak-power lasers. These include low amplified spontaneous emission with high gain and high repetition rate. For the amplifier system, an average output power of 20 W was achieved at a pulse repetition rate of 100 kHz, which corresponds to an output pulse energy of 200 μJ with an output pulse width of 2 ps.
