Paper Abstract

Review of thermo-optic effects in gain media of diode end pumped lasers is presented. Degradation in beam quality due to these effects is analyzed theoretically and verified in experiments. The slit scan method was implemented for registration of intensity profiles along the caustics of laser beam. The M2 parameter, coherence degree, and thermal lens power of gain medium in dependence on pumping rate, were determined using Wigner transform and ABCD methods. Investigations of neodymium lasers (Nd:YVO4, Nd:YAP) operating in free running or Q-switching regimes were carried out. Detrimental role of up-conversion processes for Nd:YAP laser was shown.
