摘　　要：氧碘化学激光器由于复杂的动力学因素 ,激光介质的增益分布通常是不均匀的 ,这就使得激光输出功率并不完全随着激光输出孔径成线性增加 ,也由于这种增益分布的不均匀性 ,即使在激光输出孔径不变的情况下 ,激光输出功率也会随着光轴位置的改变而发生变化。为此 ,在激光器工作参数固定条件下 ,通过实验描述了激光输出功率与激光输出孔径及光轴位置之间存在着的一定的依赖关系。Because of the complicated kinetic reasons, the gain distribution in laser medium is usually inhomogeneous for Chemical Oxygen Iodine Laser, it will cause the laser output power will not increased with the increasing of the laser output aperture, and it is also by the same reason, the laser output power will be varied with the position of optical axis, even if the laser output aperture keep constant. So, when the laser parameters is constant, the laser output power has the dependence on laser output aperture and position of optical axis, and this dependence is reported in this paper.
