Conversion of 9.3-9.6-micron pulsed laser radiation into the second harmonic in ZnGeP2 crystals
Abstract
A pulsed TEA CO2 laser was used to investigate the effect of pump radiation parameters (mode structure, wavelength, and pulse duration), focusing conditions, absorption coefficient, and temperature on the efficiency of conversion into the second harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Good agreement betweeen experimental and theoretical results is observed.
