摘要：

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 the enhancement factor of about five in comparison with a bulk scheme has been obtained with the asymmetric Cerenkovian configuration having the film thickness d congruent-to 5-mu-m. Extending the theory to that suitable to our experimental model, the results are well theoretically explained, expecting enhancement of the SHG power by the factor of 50 if d congruent-to 0.5-mu-m.
