Abstract

The rod geometry for high power solid state lasers has been proven to be both, reliable and reasonably inexpensive. On the other hand, setting up rod lasers with excellent beam qualities implies a number of thermal problems that have to be tackled. May be the most serious problem for isotropic crystals like Nd:YAG is the effect of depolarization and bifocusing due to thermally induced birefringence. This leads to a deterioration of the beam quality and moreover to severe problems regarding the resonator stability.
