Abstract

Results of measurement of the dispersion of the second-order optical nonlinear coefficient d11 of 2-methyl-4-nitroaniline (MNA) using laser diodes as light sources are presented over a wavelength range of 1.20 to 1.54 μm. The nonlinear optical coefficient strongly depends on wavelength, exhibiting a resonance enhancement. We also report the first observation of multiple-reflection effects in optical second-harmonic generation. The observation has been made possible by the use of a single-mode laser diode as a light source. The experimental results are in excellent agreement with a theoretical analysis which takes account of the multiple reflections of both the fundamental and second-harmonic waves.
