Abstract
We present here the quasi-phase-matched second-harmonic (SH) light of holographic all-optical poling measured along the off-axis direction of the wave vector of with , where is the wave vector of ω writing beam, is the wave vector of writing beam, and is the wave-vector mismatch whose vector is parallel to . As expected, of the phase-mismatched condition gave rise to a very low SH signal. Furthermore, tensor components of gratings were analyzed, and the contribution of the photoisomeric state of the cis configuration of azobenzene chromophore studied was discussed.
