Paper Abstract

Noncollinear second harmonic generation (SHG) of Nd:YAG laser in 2- methy1-4-nitroaniline (MNA) was observed. The intensities of the SHG varied depending on the crossing angles of the two incident beams. The maximum SHG tensor component, d11=235X10-12(m/v), was determined by a new estimation. The photorefractive index change in the MNA crystal was estimated as 0.009 at light intensity increase 18(MW/cm2). The light beam diffraction at the transient grating was observed by the inter-ference of the two incident beams.
