Abstract
An investigation was made of superluminescent optical parametric oscillators generating visible light when ADP and KDP crystals were pumped with the third and fourth harmonics of a neodymium laser. The conversion efficiency was 70% and the output energy in the form of parametric waves was 0.35 J. The advantages of the third harmonic of a neodymium laser as the pump radiation, over the fourth harmonic, were demonstrated.
