Er:YAG triangular ring laser resonantly pumped by a 1470 nm laser diode

摘要

An Er:YAG triangular ring laser resonantly pumped by a 1470 nm laser diode was reported. 7.28 W continuous-wave output power at 1645 nm was obtained by using a triangular ring resonator. In the Q-switched mode, the Er:YAG laser generated pulse energies from 6.05 mJ to 16.6 mJ at 1645 nm when pulse repetition rates change from 1 kHz to 200 Hz. By inserting an etalon into the resonator, the Er:YAG laser yielded Q-switched energies from 1.714 mJ to 5.1 mJ at 1617 nm when pulse repetition rates change from 1 kHz to 200 Hz.
