Abstract
The laser performance of Neodymium-doped potassium gadolinium tungstate (Nd :KGd(WO4)(2)) crystal was studied by using Ti:Sapphire laser as the pump so urce. The maximum optical-to-optical efficiencies for the 1.067 and 1.3 mum laser outputs were measured to be 60% and 32.3%, respectively. The interna l loss coefficient of the crystal for 1.056 mum laser was estimated to be a s low as 0.004 cm(-1). The oscillation thresholds at 1.067 and 1.3 mum for different output transmittances are also given.
