Abstract

Using a low non-saturable loss Bragg-reflector-based semiconductor saturable mirror, a passively Q-switched Er:Lu2O3 ceramic laser at 2.7 μm demonstrated short pulse-width and efficient operation, generating stable pulses of 70 ns pulse-width and ~71 kHz repetition rates. Over 692 mW of average output power was measured, corresponding to a pulse energy of ~9.8 μJ. In a modified resonator design of reduced round-trip time, pulses of 32 ns duration were generated. The achieved results suggest that Er:Lu2O3 ceramic could be a promising gain medium for efficient and high power pulsed laser generation at 2.7 μm. The prospects for further improvement in laser performance at this wavelength are discussed. View Full-Text
