We report on an intracavity optical parametric oscillator (OPO) placed with
in a compact diode-pumped Nd:YALO laser cavity. This OPO utilizes a pair of
RTP crystals, which are diffusion bonded together in a walk-off-compensate
d configuration. We have generated up to 21.4 W of 2-mu m radiation, operat
ing in a few-kilohertz range. (C) 2000 Optical Society of America.
