Paper Abstract

In this article we describe an efficient method of the compensation of thermally induced birefringence in high power Nd:YAG rod lasers. Losses at a resonator internal polarizer due to depolarization in the rods are reduced, and a polarized cw laser with an output power of 300 W is realized. Resonators with a small stability range and therefore beam quality near the diffraction limit are introduced. To improve the variability and stability of such resonators an adaptive high reflecting mirror is used as resonator mirror. The maximum average output power of the resonator with adaptive mirror is 145 W at a beam quality of M2 equalsV 2.
