Q-switched Er:YAG lasers resonantly pumped by Erbium fiber laser

Resonantly pumped single frequency Er:YAG laser at 1645 nm

“…Continuous wave lasers at 1.6 µm are useful for a variety of remote sensing applications, including the measurement of wind field velocities using eye safe coherent laser radar [1,2].Transitions from the 4 I 13/2 to the 4 I 15/2 energy level in Er 3+ are well known to pro duce emission in the 1.5-1.6 µm region. Er:YAG is an attractive laser medium for a hybrid laser owing to its robust thermomechanical properties.…”

Resonantly pumped continuous wave Er:YAP laser

“…Continuous wave lasers at 1.6 µm are useful for a variety of remote sensing applications, including the measurement of wind field velocities using eye safe coherent laser radar [1][2][3]. Crystals with Er 3+ doping are attractive active materials for such developments [4][5].…”
