Diode-Pumped and passively Q-switched Er:YAG Laser emitting at 1617 nm

Abstract : We present laser operation of a 750 μm diameter Er:YAG single crystal fibers pumped at 1470 nm. Laser output performances are numerically simulated, experimentally measured and compared. In Passive Q-switch regime, we obtained pulse energy of 180 μJ around 500 Hz at 1617 nm without any spectral selecting element. Pulse duration is 33 ns. By controlling the saturable absorber temperature, we succeeded to improve the output energy up to 270 μJ. These results show the interesting potential of Er:YAG single crystal fiber for compact and low power consumption rangefinders.
