摘要
Frequency doubling of an Er:YAG laser beam is observed by using a vinylidene cyanide/vinyl acetate copolymer. The nonlinear susceptibility X(2)eff is evaluated to be 5.6 × 10-7 esu, which is 2.8 times larger than that of LiNbO3 crystal. The dependence of the measured X(2)eff on the poling process is analyzed based on a theoretical model. © 1990 Optical Society of America.
