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 × 10−4 and 2 × 104 W/cm2. We discuss the detrimental effects of BLIIRA on the efficiency of intracavity frequency doubling and the threshold for parametric oscillation.
