Abstract

In this paper, thermal effects in double-end pumped Nd:YVO4 laser crystal have been investigated. The analytical expression for temperature distribution and thermo-optic effects such as temperature-dependent change of refractive index (dn/dT effect) and end effect have been calculated and the results then applied to Nd:YVO4 crystal., Our analytical model compared with exact numerical calculations and good consistency has been shown.

 

Key words: Double end pumped, thermo-optic effects, Nd:YVO4 crystal.
