摘要
针对大能量多波段皮秒激光器的技术要求,提出了采用新型无独立单选模块再生放大技术,研究和分析了高功率密度下大能量激光放大系统的抗激光损伤技术、高效倍频、和频及四倍频技术。在重复频率10 Hz时,实现1064μnm输出单脉冲能量239.8 mJ,放大倍数达到108倍,峰值功率密度为40 GW/cm2以上。
For the technical requirements of large energy multi-band picosecond laser,the regenerative amplification technology of new non-independent radio modules is proposed,laser damage resistance technology,efficient frequency doubling,sum frequency and quadruplicated frequency technology of large energy laser amplifier system were re-searched and analyzed under high power density.When the repetition frequency is 10 Hz,the output pulse energy of 1064 μm is 239.8 mJ,magnification reaches to 108 times,the peak power density is above 40 GW/cm2.
