Experimental Determination of Two-Photon and Other Nonlinear Absorption in Ultraviolet and Infrared Window Materials.

Abstract

Experimental determination of two photon absorption cross section in a variety of window materials is carried out with picosecond harmonic pulses from a mode-locked Nd-YAG laser system, with nanosecond pulses from a combined ruby-dye laser system, and with a subnanosecond CO2-laser pulses. The measurements at 10 micrometers concentrate on the properties of the conduction and valence band of InSb. The measurements of the two photon absorption cross section in the near and far ultraviolet have covered a series of alkali halides, and will be extended to other fluoride and oxide UV window materials.
