介绍了-种高光束质量、高峰值功率的二极管抽运主振荡功率放大器(MOPA)系统.通过对抽运均匀性的优化及放大特性的研究,应用了像传递和相位共轭等技术,达到了重复频率40 Hz,单脉冲能量400mJ,脉冲宽度约7ns,光束质量优于2倍衍射极限的指标.

A diode-pump ΜΟΡΑ system with high beam quality and high peak power is introduced in this article. The amplification character of the laser is studied By optimizing the pumping structure and using the image transmission and phase conjugation technology, the laser output reaches 400mJ per pulse at a typical repetition rate of 40 Hz, and pulse width is 7 ns, beam quality is better than 2 times diffraction limit.
