Oxide Ceramic Laser

Abstract

The long range goal of the current research program is to develop an intermediate gain, solid laser material which has an emission line width between that of neodymium-doped glass and neodymium-doped yttrium aluminum garnet single crystals. Such material should be suitable for generating high average power combined with high peak power. In order to achieve this goal, experimental and theoretical work has been done in the past 18 months to (1) develop a process to reproducibly fabricate Nd-doped Yttralox(TN), a polycrystalline oxide ceramic comprised of 89 mole % Y2O3, 10% ThO2, and 1% Nd2O3 in solid solution, of improved optical quality, (2) understand the densification process with respect to the kinetics of porosity change and (3) evaluate Nd-doped Yttralox rods as a potential laser material by means of optical measurements.
