Abstract

In this paper, we report a compact mid-IR intracavity OPO, which has 4.1 W of 3.5-micron output from a non-critically phase-matched (NCPM), type II, KTiOAsO4 (KTA) optical parametric oscillator (OPO). This KTA OPO was pumped within the cavity of a Q-switched diode-pumped Nd:YALO laser operating at 10 kHz. We adopted the simplest configuration with a compact diode-pumped Nd:YALO module pumping the singly resonant KTA OPO. Besides 4.1 W of 3.5 um, 10.9 W of 1.5 micron and 11.3 W of 1-micron radiation were obtained simultaneously.
