首次报道了用窄谱InGaAsP/InP二极管条叠共振泵浦掺Er ~（3+）钒酸钇单晶，获得了人眼安全的1593.5 nm激光输出。在1534 nm泵浦下，获得了最大斜率效率为70%左右，最大准连续（Q-CW）功率为59.8 W的Er 3+：YVO 4激光器。
Laser operation of an eyesafe 1593.5-nm laser based on Er3+-doped yttrium orthovanadate single crystal resonantly-pumped by a spectrally-narrowed InGaAsP/InP diode bar stack is demonstrated for the first time. Cryogenically-cooled Er3+:YVO4 laser pumped at 1534 nm performed with maximum slope efficiency of ∼ 70% and maximum quasi-continuous-wave (Q-CW) power of 59.8 W.
