Abstract
Second-harmonic generation is enhanced with both symmetric and asymmetric slab-guides composed of vinylidene cyanide/vinyl acetate copolymer film and a fused silica in the Cerenkov radiation scheme at Nd:YAG 1.06 mu m and Er:YAG 2.94 mu m laser lines. At 1.06 mu m wavelength an enhancement factor of about five in comparison with a bulk scheme has been obtained with the symmetrical Cerenkovian configuration having the film thickness d approximately=5 mu m. Extending the theory to the experimental model presented, the results are well explained theoretically, and an enhancement of the SHG power by a factor of 50 can be expected if d approximately=0.5 mu m.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
