Paper Abstract

The analysis of pump geometry presented in this work allowed to determine optimal conditions of excitations of diode pumped solid state lasers for oscillation of quasi-Gaussian TEM00 mode. There appears the existence of weak transverse mode structure. The heterodyne analysis for two kinds of laser: Nd:YAG and Nd:YVO4 was performed. We found the strong mode competition effect decreasing long- term frequency stability of the lasers. The offset frequency stability between two Nd:YVO4 lasers for short averaging time is 10-10. Using offset frequency feedback loop, stability of the level of 300kHz has been obtained.
