摘要

A comprehensive investigation is carried out to compare the spectroscopic properties,absorption saturation behaviors and lasing properties of a Yb ion in tetragonal LuPO4 and LuVO4 isomorphic crystals.Significant distinctions are revealed in many aspects of the lasing behavior for the Yb ion doped in the two crystal hosts,and Yb:LuPO4 proves to be superior to Yb:LuVO4 since it enables efficient laser action to be much more easily achieved.With a 0.6 mm thick crystal plate of Yb:LuPO4,an output power of 3.30 W can be generated with an optical-optical conversion efficiency of 50.8％;whereas with a 2 mm long miniature crystal rod,the output power produced can reach 8.35 W with an optical-optical conversion efficiency of 46.7％.
