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 4 k ω k 2 ω + Δ k with Δ k = 0 , where k ω is the wave vector of ω writing beam, k 2 ω is the wave vector of 2 ω writing beam, and Δ k is the wave-vector mismatch whose vector is parallel to k ω . As expected, Δ k 0 of the phase-mismatched condition gave rise to a very low SH signal. Furthermore, tensor components of χ ( 2 ) gratings were analyzed, and the contribution of the photoisomeric state of the cis configuration of azobenzene chromophore studied was discussed.
