Abstract

We have a developed 2-adamantylamino-5-nitropyridine (AANP) crystal for use in frequency converters. By second-harmonic generation at 1.064 μm coefficients of d31 and d33 were deter-mined to be 80 and 60pm/v, respectively. Angle-tuned phase-matched second-harmonic genera-tion was demonstrated using a lmm AANP bulk crystal at 1.064 μm and 1.32 μm. Its conver-sion efficiency was found to be about 2×10^-³W^-¹ and 10^-³W^-¹, respectively. By using the AANP crystal, optical parametric interaction around 1.3 μm wavelength was also observed.
