抄録

Noncollinear second harmonic generation (SHG) of Nd:YAG laser in 2- methyl-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=235×10^-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 interference of the two incident beams.
