42,497 CAN 4A ABSTRACT This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical. energy at another frequency. Laser techniques have been developed to a great extent and it is possible to obtain various kinds of laser light by utilizing solid, gas, and liquid media. Laser light having various wavelengths is often desired and in some cases, a laser tight exhibiting a continuous spectrum over a certain range of wavelengths is desired. One means for converting coherent laser light of a fundamental frequency into laser light of a wavelength having a frequency twice the fundamental frequency (i.e., the second harmonic) involves passing the laser light through a nonlinear optical crystal. This invention involves devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, crystalline 5-chloro-2-nitroaniline that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the 5-chloro-2-nitroaniline, and output means for utilizing the second harmonic frequency.
