Abstract

A spectral and temperature investigation of fast-grown KDP crystals under high fluence, 355 nm laser irradiation is discussed. Pump-and-probe Raman spectroscopy indicate transient changes of the vibrational spectrum. Photothermal deflection experiments provide information on the temporal behavior of the temperature changes. The presence of emission in the visible and NIR spectral regions is attributed to the presence of impurities and/or defects in the crystal.
