Paper Abstract

Thulium and holmium-doped yttrium aluminum garnet (YAG) ceramic materials are investigated. Compared with YAG crystal, there is hardly any spectroscopic difference between ceramic and crystal at the same doping level. Laser oscillation was successfully carried out under quasicontinuous- wave diode pumping. Optical-to-optical efficiency higher than 5% was achieved. It was calculated that total absorbed power hardly changes around 783 nm with a bandwidth of about 7 nm using a diode array of 3.5-nm linewidth as a pump source.
