Blue-light induced infrared absorption in KNbO3

Creators

Abstract

We have used a high-finesse cavity to measure the cw intensity dependence and dynamics of blue-light-induced infrared absorption (BLIIRA) in KNbO3 crystals for blue-light intensities between 7 x 10^-4 and 2 x 10^4 W/cm^2. We discuss the detrimental effects of BLIIRA on the efficiency of intracavity frequency doubling and the threshold for parametric oscillation.

We also thank Greg Mizell of Virgo Optics for helpful discussions and the generous loan of many KNbO3 crystals used in this study. This research was funded by the U.S. Office of Naval Research and by the National Science Foundation.
