掺铒激光玻璃能实现 1 .5 4μm波长的激光 ,对人眼安全 ,又处于通信窗口 ,可以应用于通信和测距仪等方面。我们利用自己制备的 Er,Yb共掺磷酸盐玻璃 (铒离子荧光寿命τ =7.5 ms,峰值发射截面σem =0 .8× 1 0 - 2 0 cm2 ,Yb2 O3浓度 :1 5 .6 wt- % ,Er2 O2 浓度 :0 .5 wt- % ) Erbium-doped laser glass can achieve 1.54μm wavelength laser, eye-safe, but also in the communication window, can be used in communications and range finder and so on. We use the Er, Yb co-doped phosphate glass prepared by ourselves (erbium ion fluorescence lifetime τ = 7.5 ms, peak emission cross section σem = 0.8 × 10-20 cm 2, Yb 2 O 3 concentration: 1.56 wt-% , Er 2 O 2 concentration: 0.5 wt-%)
