Advances in the spectral coverage of tunable continuous-wave Optical Parametric Oscillators

摘要

We discuss principles, design challenges, performance highlights as well as current limitations of state-of-the-art widely tunable continuous-wave optical parametric oscillators sought to be practical for implementation as turn-key systems. Employing a flexible two-stage design concept that can be adapted to several single-frequency laser pump sources, we demonstrate how a wavelength range from 450 nm up to 3500 nm can be covered almost seamlessly. Emerging key-applications in the realm of quantum technology, like fundamental studies of novel color centers in diamond, are presented in an illustrative manner.
