Preparation of Rare Earth Doped Laser Materials and Er, Tm, Ho: Y LiF4 Laser Rods.
Abstract
This work describes two main activities in preparation of special materials for solid state lasers. The first portion is concerned with Ce3+, Eu2+, Yb2+ and Pr3+ doped hosts to examine possible lasing schemes in the green region based on d-f type lasing. Hosts were chosen with particular structures, coordination and charge to obtain band fluorescence centered near 5000 A. The second portion was directed towards preparations of Er, Tm, Ho doped YLiF4 to examine further the lasing at 2.06 micrometers under Q-switching conditions. Ten new ( 3 x 30 ) mm laser rods were delivered to U. S. Army Electronics Command for testing. The compositions of these rods differed in the amount of Tm and Ho. Preparation of all fluoride compounds was from commercially available 5-9's purity oxides. Single crystal growth was achieved by top seeded solution in an HF atmosphere.
