Crystal Growth of Diode Pumpable Laser Materials.

Abstract

This program describes the preparation and crystal growth of materials which may be particularly suitable for laser diode pumping. Disordered crystal structures with broadened absorption and emission bands were investigated. About 60 growth runs were achieved with oxide hosts and ten with fluoride hosts. The laser dopants were chosen to yield highly efficient 1-5 micrometers lasers, possible tunable laser in the 2-3 micrometers region, all with good temperature stability. Materials were all grown, fabricated, and coated at Airtron. The active and passive laser tests were performed at the Naval Research Laboratory. Several oxides were identified and gave excellent results with Ho, Er, or Tm doping. U(3+):YLiF4 was the most interesting among the fluorides. The results of these investigations were presented at various conferences.
