Coupled-cavity concept applied to a highly compact single-frequency laser operating in the 2 μm spectral region

Appl Opt. 2011 Apr 1;50(10):1329-32. doi: 10.1364/AO.50.001329.

Abstract

We present a highly compact and cost-efficient Tm:YAP laser setup supporting single-frequency operation at a significantly high efficiency. The coupled-cavity concept was used to design a single-frequency laser operating at 1990 nm. Single-frequency output power of 784 mW was obtained when the absorbed pumping power was 2.4 W. The optical-to-optical efficiency was 33%, and the slope efficiency was 52%.
