Nonlinear susceptibility and damage thresholds of organic MBA-NP crystals

Abstract
The nonlinear optical behaviour of the organic crystal MBA-NP has been investigated at 1064 and 532 nm, with both nanosecond and picosecond pulses. The second-order effective susceptibility for second harmonic generation, and the damage thresholds compare favourably with those of most inorganic crystals. Two-photon absorption is rather small, while stimulated Raman scattering, which can be excited only with the 532 nm radiation, is strongly dependent on the orientation of the sample.
