Abstract

Compounds capable of second harmonic generation are provided for use in a nonlinear optical device, in combination, a harmonic-generating medium, means for introducing coherent radiation into said harmonic-generating medium, and means for utilizing the coherent radiation emitted from said medium, wherein said medium consists essentially of a crystalline body of a compound of the formula: <IMAGE> wherein n is about 0-5, m is about 0-5, R1 is individually -NO2, -OR2, -CN, -NR2R3, (C1-C5)alkyl, -CO2H, halo, <IMAGE> R is individually -NO2, -CH3, -OR2, -NR2R3, -CN, <IMAGE> and X is -O-, -S-, -N(R2)-, <IMAGE> and wherein R2 and R3 are individually H, (C1-C5)alkyl, aryl or ar(C1-C5)alkyl.
