【摘要】：文章报导了基于大基模体积的高能量飞秒钛宝石激光再生放大器的设计与实验研究,在重复频率10 Hz、抽运能量60 mJ的激励下,得到了单脉冲能量17.4 mJ的种子脉冲放大结果,压缩后的脉冲宽度为40.6 fs,能量为13.9 mJ.借助于此大基模体积再生腔,仅增加一级多通放大,实现了峰值功率达1.9 TW飞秒激光脉冲输出.结果表明,大模体积再生放大不仅降低了后续放大对抽运能量的要求,也可以单独压缩实现再生腔直接输出10 mJ量级的飞秒激光脉冲,是大能量高峰值功率飞秒激光系统的优质前端.
[Abstract]:This paper reports the design and experimental study of a high energy femtosecond Ti: sapphire laser regenerative amplifier based on large base mode volume. Under the excitation of 10 Hz repetition rate and 60 MJ pump energy, the single pulse energy of 17.4 MJ is obtained. The pulse width after compression is 40.6 fs and the energy is 13.9 mJ.The peak power of 1.9 TW femtosecond laser pulse output is achieved by using this large base mode volume regenerative cavity and only one stage multipass amplification is added. Large mode volume regenerative amplification not only reduces the requirement of subsequent amplification to pump energy, but also can compress the regenerated cavity directly to output 10mJ femtosecond laser pulses. It is a high quality front end of femtosecond laser system with large energy and high peak power.
