摘要
以简单的火花间隙作为放电开关 ,建立了一种用于 ps脉冲激光放大的大口径放电泵浦 Kr F准分子激光器。该激光器的有效增益口径截面为 4 cm× 3cm,在自由运转情况下最大激光输出能量为 1.3J,脉宽2 0 ns。用作 ps放大器时 ,利用光学偏振放大方式获得了激光能量 14 0 m J,脉冲宽度 10 ps的激光输出。利用 Xe
A large aperture discharge-pumped KrF laser module with simple spark gaps was developed. The laser beam cross section of 4cm×3cm and the maximum laser output energy of 1.3J in 20ns were obtained at the charging voltage of 30kV and gas mixtures of ∶∶=0.1∶2∶97.9. The gain and absorption coefficients at different gas mixtures were measured with a frequency doubled dye laser pumped by a XeCl laser. Using this laser module as a ps amplifier, the output energy of 140mJ in 10ps was obtained.
