Abstract
Devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, a crystalline N,N'-substituted barbituric acid that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the N,N'-substituted barbituric acid, and output means for utilizing the second harmonic frequency.
