✦ Synopsis

Laser operation of an eyesafe 1593.5-nm laser based on Er 3+ -doped yttrium orthovanadate single crystal resonantlypumped by a spectrally-narrowed InGaAsP/InP diode bar stack is demonstrated for the first time. Cryogenicallycooled Er 3+ :YVO4 laser pumped at 1534 nm performed with maximum slope efficiency of ∼ 70% and maximum quasicontinuous-wave (Q-CW) power of 59.8 W. Q-CW output power, W 60 50 40 30 20 10
