摘要
制备了掺Yb:硼酸盐和Yb:磷酸盐玻璃,并研究了它们的玻璃物理性质和光谱性质.掺Yb:磷酸盐玻璃的热机械性质优于掺Yb:硼酸盐玻璃.掺Yb:硼酸盐玻璃的受激发射截面和荧光寿命分别为0.53×10-20 cm2和0.85 ms.掺Yb:磷酸盐玻璃的受激发射截面和荧光寿命分别为0.45×10-20 cm2和1.8 ms.作为激光材料,掺Yb:磷酸盐玻璃的综合性能优于掺Yb:硼酸盐玻璃.用钛宝石激光器抽运Yb:硼酸盐玻璃实现8 mW准连续激光输出.用波长为976 nm,6 W的LD抽运Yb:磷酸盐玻璃获得了62 mW的连续激光输出,其斜率效率为4.4%.
Abstract
Physical, spectral and laser properties of ytterbium borate and phosphate laser glasses were researched. Assessing from thermal mechanical property, nonlinear property, glass transition temperature and spectroscopic properties of both glasses, it is found that as a laser medium ytterbium phosphate glass is a better candidate than ytterbium borate glass. Pumped by a 6 W, 974 nm laser diode, tunable cw laser with 62 mW maximum output power and 4.4% slope efficiency was achieved in the ytterbium phosphate glass. In ytterbium borate glass, pumped by 1 W, 940 nm Ti∶sapphire laser 8 mW quasi-cw laser output of 8 mW was obtained. The laser performance of ytterbium phosphate glass is confirmed to be better than that of ytterbium borate glass.
