Er3+/Yb3+共掺杂磷酸盐玻璃–作为LD泵浦的1540nm眼睛安全辐射源，可以发射直接在激光测距仪和电信通信中使用的1540nm眼睛安全激光辐射
1540um，Er3+/Yb3+共掺杂磷酸盐玻璃激光器作为一种对人眼安全的波长激光器，由于其紧凑和低成本（例如激光产生和信号放大）而备受关注，因为1540nm的波长正好位于眼睛安全和光纤通信窗口的位置。1540nm激光器已用于测距仪，雷达，目标识别。Er3+/Yb3+共掺杂磷酸盐玻璃与无源被动Q开关钴尖晶石共同获得1540nm脉冲固态激光器。
Er3+发射跃迁发生在与4I13/2→4I15/2相对应的该波长范围内。但是，Er3+吸收本身太弱而不能直接泵浦，因此需要能量转移。最有效的是在2F7/2→2F5/2跃迁吸收下的Yb3+离子，然后是能量转移到 4I11/2 Er3+能级和快速的非辐射跃迁到Er3+ 4I13/2能级，从而发出预期的荧光。Er，Yb：辐射输出为1540 nm的玻璃激光器不需要添加其他组件。
