We report the experimental realization of a new type of optical parametric oscillator in which oscillation is
achieved by polarization rotation in a linear retarder, followed by nonlinear polarization mixing. The mixing
is performed by a type II degenerate parametric downconversion in a periodically poled KTP crystal pumped
by a 1064 nm pulsed Nd:YAG pump. A single, linearly polarized beam, precisely at the degenerate wave-
length is generated. The output spectrum has a narrow linewidth (below the instrumentation bandwidth of
1 nm) and is highly stable with respect to variations in the crystal temperature. 2005 Optical Society of
OCIS codes: 190.4970, 190.4360.
Quasi-phase-matched frequency conversion using pe-
riodically poled crystals has proved to be a mature
technology for generating coherent light where con-
ventional lasers are unavailable. Optical parametric
