摘要
The laser performance of Neodymium-doped potassium gadolinium tungstate(Nd:KGd(WO4)2)crystal was studied by using Ti:Sapphire laser as the pump source.The maximum optical-to-optical efficiencies for the 1.067 and 1.3μm laser outputs were measured to be 60%and 32.3%,respectively.The internal loss coefficient of the crystal for 1.067μm laser was estimated to be as low as 0.004 cm-1.The oscillation thresholds at 1.067 and 1.3μm for different output transmittances are also given.
