Title:
ORGANIC NONLINEAR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JPH0333834
Kind Code:
A
Abstract:
PURPOSE:To obtain the quadratic nonlinear optical material which has a large nonlinear optical constant, is stable in the atm. air, is transparent in a short wavelength region, and has excellent crystallinity and crystal workability by using an aminate crystal consisting of amino acid and inorg. acid. CONSTITUTION:This optical material consists of the aminate obtd. from at least one kind of the amino acids selected from valine, tryptophan, leucine, threnione and lysine and at least one kind of the inorg. acids selected from phosphoric acid, iodinic acid and boric acid. The crystal of the valine phosphate is obtd. by mixing, for example, valine and phosphoric acid in an aq. soln. of equal molar ratio, then lowering the temp. to attain a supersatd. state in this case. The quadratic nonlinear optical which has the large nonlinear optical constant, is stable in the atm. air, is transparent up to about 270nm and is excellent in crystallinity and crystal workability is obtd. in this way.
