| 摘 要： | 讨论了双向光泵浦XeF(C-A)激光技术，给出了双向泵浦情况下的XeF2光解离波图像。在双向泵浦条件下XeF(C-A)激光输出能量提高了近3倍，最大输出达到3.3 J，激光脉宽增加到1 100 ns。激光输出特性受XeF2初始浓度的显著影响，激光形成时间随XeF2初始浓度增大而加长，激光脉宽先增大后减小，激光近场光斑呈现出不同的形状，由方形变化为“X”形状。

| Abstract: | The technology of XeF(C-A) laser pumped by two counter optical sources is discussed and the photographes of the XeF_2 photodissociation waves propagating from two directions are given.The output energy of XeF(C-A) laser is enhanced under two pump sources condition,which is 3.3 J with the laser pulse duration of 1 100 ns.The output properties of XeF(C-A) laser are obviously affected by the initial XeF_2 concentration.The laser formation time increases with the increase of the initial XeF_2 concentration and the near-field pattern of the laser beams has different profiles under different XeF_2 concentration. |
