  This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical energy at another frequency. Laser techniques have been developed so that it is possible to obtain a limited number of fundamental frequencies of coherent laser light by utilizing solid, gas, and liquid media. However, in many applications, laser light having frequencies not among the fundamental frequencies obtainable is required, and in some cases laser light exhibiting a continuous spectrum over a certain range of frequencies is required. The possibility of using organic materials in nonlinear optical devices has generated much interest recently because a large number of organic materials are available for investigation and because they do not have the bandwidth limitations of inorganic materials. This invention provides 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.

  本发明涉及将一种频率的光能转换为另一种频率的光能的非线性光学设备材料。激光技术的发展使人们有可能通过利用固体、气体和液体介质获得数量有限的基频相干激光光。然而，在许多应用中，需要的激光频率并不在可获得的基频范围内，在某些情况下，还需要在一定频率范围内显示连续光谱的激光。最近，人们对在非线性光学设备中使用有机材料的可能性产生了浓厚的兴趣，因为有大量的有机材料可供研究，而且它们没有无机材料的带宽限制。本发明提供了产生相干二次谐波光辐射的装置和方法。这些装置包括一个固定基频的相干光辐射激光源，一个偏心结晶、非手性、直链 N-硝基苯基氨甲酰化合物，将激光输出辐射引导到偏心结晶、非手性、直链 N-硝基苯基氨甲酰化合物上的装置，以及利用二次谐波频率的输出装置。本文还描述了可用于上述装置和方法的 N-硝基苯基氨甲酰化合物及其偏心晶体。
