Linear and Nonlinear Optical Properties of New Organic Materials

Abstract

Abstract Single crystals of new organic nonlinear optical materials, N-(2,4-dinitrophenyl)-1-chloro-3-phenyl-2-propanamine(DNCPA) and N-(5-nitro-2-pyridyl)leucinol(NPLO) have been grown by a seeded solution growth technique. Linear and nonlinear optical properties of these materials have been investigated. Angle-tuned type I and type II phase matching for frequency doubling of 1064 nm radiation at room temperature were achieved for DNCPA and NPLO crystals. The effective nonlinear coefficients were d eff = 0.13 pm/V (type I), d eff = 1.1 pm/V (type II) for DNCPA and d eff = 40 pm/V (type I), d eff = 3.0 pm/V (type II) for NPLO, respectively.
