Basic properties of KDP related to the frequency conversion of 1 µm laser radiation

We present calculations of various basic properties of KDP related to the generation of the second, third, and fourth harmonics of 1 μm laser radiation. For five different conversion processes we tabulate the phase-matching angles, the sensitivities to angular mismatch, wavelength and temperature, and related quantities. All calculations are based on experimentally determined refractive indexes and refractive-index temperature derivatives. Calculations are compared with recent experimental results whenever possible, and are generally in good agreement.
