报道了自行建立的一台钛宝石再生放大器，它将作为整套TW系统的首级放大装置，并通过实验研究了它在自由运转条件下的能量和时间工作特性：获得了10％的斜率效率；在45mJ泵浦下得到了4mJ的脉冲激光输出；脉冲建立时间稳定在350ns左右，重复频率为10Hz。这些性能指标初步验证了再生放大器的腔结构和光学布置的合理性，其稳定运转保证了将进行的种子注入和放大。
Reported a self-developed titanium sapphire regenerative amplifier, which will serve as the first stage of the TW system amplification device and experimentally studied its free-running conditions of energy and time operating characteristics: obtained 10% slope efficiency; The 4mJ pulse laser output was obtained at 45mJ pump. The pulse setup time was stable at 350ns and the repetition frequency was 10Hz. These performance indicators preliminarily verify the rationality of the cavity structure and optical arrangement of the regenerative amplifier, and its stable operation ensures the seeds to be injected and amplified.
