Abstract

A new second-order nonlinear optical organic Material, 8-(4′-acetylphenyl)-l,4-dioxa-8-azaspiro[4.5]decane (APDA) was synthesized as a frequency doubler emitting blue light. Its crystal growth, linear and non-linear optical properties were evaluated. The APDA crystal has a short cutoff wavelength of 384 nm and high nonlinear optical coefficients d33=50 pm/V and d32=7 pm/V. The crystal is phase matchable below wavelengths of 800nm, and its maximum effective nonlinear coefficient is 14.9 pm/V. Type I phase-Matched second harmonic generations can be carried out with YAG and Ti-sapphire laser pumping.
