摘　　要：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。A Ti: sapphire regenerative amplifier developed recently as a key part of the whole on-developing table-top TW laser system is reported. Experimentally, its energy and temporal performance under the condition of free- running is investigated: the slope efficiency of 10% and the output pulse energy as high as 4 mJ are achieved under a pumping energy of 45 mJ; The build-up time of the output laser pulse is steadily 350 ns and its repetition rate is 10 Hz. From these indexes it shows that the cavity structure and theoptical setup of the regenerative amplifier are good and its steady operation makes the injection and amplification of the seed pulse reliable.
