Optical characteristics and prospects for the use of p-nitro-p'-methylbenzalaniline crystals in nonlinear optics

Single crystals of p-nitro-p'-methylbenzalaniline (NMBA) were grown by crystallization from a solution. Measurements were made of the components of the nonlinear susceptibility tensor and the frequency dependence of the refractive indices. The largest components of the nonlinear susceptibility tensor of NMBA, d₃₃ and d₃₂, were respectively 250 and 24 times greater than d₁₁(SiO₂). The use of NMBA crystals in frequency doubling was studied.
