Paper Abstract

Ceramic laser gain materials have been in development since the 1960's but it was not until the resurgence in research and development in the 1990's that they showcased equivalent laser performance to their single crystal counterparts. Ceramics offer numerous distinctive advantages over single crystal and are considered to be the key enabler in power scaling of solid state lasers. Ceramics can be made larger, at lower cost, and with additional degrees of engineering design freedom than single crystals, such as higher doping concentration, more uniform or tailored distribution of dopants, and feasibility to be fabricated into monolithic composite structures without bonding. At Raytheon, powder processing methodology has matured to meet the optical requirement, scale-up challenge, and laser performance characteristics in Yb, Nd, and Er doped ceramic YAG materials. This communication presents the latest results obtained by Raytheon on the US fabricated ceramic laser materials.
