Abstract

Deformable bimorph mirrors with high damage threshold dielectric coatings are demonstrated as both intra- and extracavity components with a pulsed energy diode-pumped Nd:YAG zigzag slab laser operating at the 150 mJ level. Two resonator configurations were tested for intra-cavity operation; with a plane-plane resonator the far-field brightness was enhanced by up to a factor of 1.5, whilst with a cross-Porro resonator an enhancement of up to 2.2 was achieved. As an extracavity component far-field beam steering of ±2 mrad was demonstrated. © 2009 SPIE.
