Title

Observation of two-dimensional quadratic spatial solitons in type I potassium niobate

Abstract

A c-plate KNbO3 crystal cut for non-critical phase matching for an a-polarized fundamental at a wavelength of 985 nm for a crystal temperature of 31.4 °C was studied. Quadratic spatial solitons (QSS) were formed while exiting the back face of the KNbO3 crystal. The beam waist of the fundamental field trapped in the QSS was 19.75 μm, which was smaller than that of the freely diffracting beam. Due to the low intensity threshold requirements for QSS formation and the sensitivity of the vidicon camera, a freely diffracting beam could not be observed at the output face of the crystal.
