Diode-pumped continuous-wave optical parametric oscillator

Abstract

So far, diode-pumped operation of continuous-wave optical parametric oscillators (cw-OPO) has been possible only by resonating two or three of the interacting waves, in order to reduce the threshold to below the available diode pump power. [1,2] We demonstrate a cw-OPO which is directly pumped by a diode-laser and is operated with a cavity which provides low losses only for the signal wave.
