The dependence of the laser output power versus the laser output aperture and optical axis position on CW COIL

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. 
