H. Mabuchi et al., BLUE-LIGHT-INDUCED INFRARED-ABSORPTION IN KNBO3, Journal of the Optical Society of America. B, Optical physics, 11(10), 1994, pp. 2023-2029
We have used a high-finesse cavity to measure the cw intensity depende
nce 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 eff
iciency of intracavity frequency doubling and the threshold for parame
tric oscillation.
