title = "400W Yb:YAG planar waveguide laser using novel unstable resonators",
abstract = "A planar waveguide laser consisting of a 13mm x 12mm x 150µm Yb:YAG core with 1mm high sapphire claddings is edge pumped using two 450W diode stacks with custom aberration correcting phase-plates. A plano-concave resonator gives 400W average power in a low-order transverse, multi-longitudinal mode beam with 75% slope efficiency, comparable to other thin disk and slab lasers. Transverse beam quality is improved through use of novel mode selective toroidal laser-cut resonator mirrors, whilst lateral beam quality is improved through the use of an unstable resonator. Uniform gain with an amplification of 3-4 per pass shows promise for amplifier operation. {\textcopyright} 2010 Copyright SPIE - The International Society for Optical Engineering.",
