Nd3+:KGd(WO4)2激光晶体的研究
Study on Laser Crystal Nd3+:KGd(WO4)2
摘要
Abstract
A series of KGd(WO4)2 powder samples with different Nd3+ doping concentrations were made and their fluorescent intensities at 1.06μm were measured.The optimal Nd3+ doping concentration has been determined.The liquid temperature curve for the system of Nd3+：KGd(WO4)2-K2WO4 was determined by means of differential thermal analysis(DTA),and large crystals of Nd3+：KGd(WO4)2 with dimensions of up to 50mm have been grown from a K2WO4 flux.From the grown crystal boule,a high-quality laser bulk crystal with dimensions of 5mm×5mm×6mm was cut out,and it's absorption spectrum has been measured.A laser output of 260mW at 1.06μm with a slope efficiency higher than 66% and a laser output of 135mW at 1.3μm with a slope efficiency up to 34.3% were obtained when this crystal was pumped by a Ti-sapphire laser.关键词
