Stable Telescopic Resonators, Unstable Resonators And New Cavity Designs Applied To High Energy Laser Engineering

In this paper we present an overview of the present state of the art in high-energy laser resonator design, with particular attention to solid state Nd:YAG lasers. A comparative review is made of the most common cavity configurations and a completely new resonator design is presented, which is a novel development of the unstable resonator concept.
