Tunable operation of a continuous intracavity frequency doubled singly resonant Optical Parametric Oscillator

Abstract

Tunable and ultra-narrow linewidth visible sources are mandatory instruments for high-resolution spectroscopy or quantum information processing applications using rare-earth ions embedded in solid-state matrices. Optical parametric oscillators (OPOs) are an especially promising approach toward this goal because of their wide tuning range and good frequency stability. Indeed, in recent years, the increased availability of novel nonlinear materials and high-power solid-state single-frequency pump sources has led to great advances in the development of CW singly resonant optical parametric oscillators (SROPOs).
