Paper Abstract

We report 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 mixing of the two polarized beams. The mixing is performed by a type II degenerate parametric down conversion in a PPKTP crystal, pumped at 1064nm by a pulsed Nd:YAG laser. A single, linearly polarized beam is generated at the degenerate wavelength. The output spectrum has a narrow linewidth (below the instrumentation bandwidth of 1nm), and is highly stable at degeneracy with respect to variations in the crystal temperature. The frequency locking is explained in terms of balanced roundtrip phase-matching condition.
