Picosecond optical parametric oscillation in bulk quasi-phase matched lithium niobate

Summary form only given. Periodically poled lithium niobate (PPLN) is an attractive nonlinear medium on account of its very large effective nonlinearity and the fact that with suitable period it can provide noncritical phase-matching for generation of any wavelengths in its transmission range. Here we report the first (to the authors' knowledge) operation of a PPLN synchronously pumped optical parametric oscillator.
