Abstract
The medium refractive index in a high-power laser resonator will vary with the radial variation of the physical quantities such as the temperature, the pressure, the current and energy, and its distribution is something of a lens-like one. As a result, the oscillation performance of the laser will be changed and the aberration of the lens-like medium will occur. According to the ray matrix theory, with a telescopic confocal unstable resonator as an example, the effect of lens-like medium in the laser resonator and its aberration correction is analyzed with the geometric method. It is pointed out that this kind of aberrations can be effectively corrected with the method proposed.
