摘要

由于晶体涂层的质量更高，在薄杆Yb:YAG激光放大器的输出处实现了8 mJ脉冲能量，重复频率为1.5 kHz，超过了该几何形状先前记录的3倍以上。在提高平均功率和保持光束质量的同时，提出采用细锥杆有源元件进一步进行能量标度。

High-energy and high average power thin-rod and thin-tapered-rod Yb:YAG laser amplifiers

8 mJ pulse energy is achieved at the output of the thin-rod Yb:YAG laser amplifier at 1.5 kHz repetition rate that is more than 3 times surpasses the previous record for this geometry due to the higher quality of the crystal coatings. It is proposed to use thin-tapered-rod active elements for further energy scaling simultaneously with average power increasing and beam quality preserving.
