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, an acentrically crystalline, achiral, straight-chain N-nitrophenyl carbamyl compound, means for directing the output radiation of the laser onto the acentrically crystalline, achiral, straight-chain N-nitrophenyl carbamyl compound, and output means for utilizing the second harmonic frequency. N-nitrophenyl carbamyl compounds, and acentric crystals thereof that are capable of being used in the aforementioned devices and method, are also described herein.
