Abstract

PURPOSE:To obtain a colorless or nearly colorless nonlinear optical material which has large SHG activity and is stable at room temp. by using a nonlinear optical material consisting of the 4-halogeno-4'-nitrobiphenyl deriv. expressed by the specific formula. CONSTITUTION:The 4-halogeno-4'-nitrobiphenyl deriv. expressed by the formula is used as the nonlinear optical material. In the formula, X denotes a halogen atom., R, R' denote a hydrogen atom. or alkyl group. This biphenyl deriv. is the colorless or nearly colorless org. compd. and has the function of the SHG conversion efficiency higher by several times to tens several times as compared to urea. The nonlinear optical material consisting of the 4-halogeno-4'- nitrobiphenyl contg. the halogen atom. as a iodine atom. has the SHG activity of 21 times the SHG activity of urea, is stable at room temp. and is applicable to a semiconductor laser as well.
