Abstract

Thermal effects of diode pumped solid-state lasers have been discussed briefly. The influence of thermal lens effect on laser output mode and beam quality, and the compensation method for thermal lens effect are briefly analyzed by means of transmission matrix optics. The functional relations between the thermal lens focal length and the beam spot size for a plano-concave stable resonator have been calculated numerically. In this paper, further experiment on the output beam quality of a laser diode pumped acousto-optic Q-switched laser has been also performed with Hartmann-Shack (H-S) wavefront sensor and Zernike mode reconstruction theory. In this way, the PV and RMS values of wavefront aberration, the frontal 35-order zernike aberrations can be acquired, and the point spread function (PSF) of beam and the distribution of circle energy can also be obtained by calculation, so the output beam quality can be known fully. Experimental results show that the wavefront aberration of laser is mainly concentrated in the frontal 15 ranks of Zernike aberration, mainly including the defocus Z3, the low-order astigmatism Z4 and Z5, and the spherical aberration Z10 because of the thermal effect of gain medium.
