| 摘 要： | 采用熔盐提拉法生长了尺寸达30 mm×25 mm×15 mm的Er3+/yb3+KGd(WO4)2透明晶体,从中切出5 mm×5 mm×3mm大小的激光器件,在室温下测试了吸收光谱,可以观察到晶体存在366,380,489,522,651,811,980 nm等吸收峰,并对之进行了能级归属.同时在980 nm激光激发下测试了荧光光谱,可以发现在1 024,1 535 nm处存在较宽的强发射峰,其半高宽分别为60和36 nm.研究结果表明,Er3+/yb3+KG(WO4)2适合于InGaAs LD(980 nm)泵浦,有可能产生1 024 nm波段及人眼安全的1 535 nm波段的可调谐激光.

| Abstract: | The Er3 /Yb3+:KGW crystal with the dimensions of 30 mm x 25 mm x 15 mm was grown from K2W2O7 solvent by modified Czochralski method. The absorption spectrum was measured at room temperature and its absorption peaks were assigned. The emission spectrum was obtained under the excitation of 980 nm. There are two broad emission bands at 1024 and 1535 nm, whose FHWM are 60 and 36 nm respectively. It shows that this crystal is suitable for InGaAs LD pumping, and may be a promising laser crystal tunable at near 1 024 and 1 535 nm. |
