Highly efficient lasing at difference frequencies is obtained in a nematic liquid crystal excited by several visible lines from a cw argon laser with a total power of 0.08-1.5 W. The maximum conversion efficiency was {approx}1% and the quadratic susceptibility was {approx}2x10{sup -6} m V{sup -1}. The field of application of the approximate mechanism of quadratic nonlinearity and frequency conversion considered in the paper requires specification. The nonlinear conversion of radiation in a nematic crystal has specific features compared to lasing at difference frequencies in solid crystals. (nonlinear optical phenomena)
