Paper Abstract

A first order quasi phase matched periodically poled LiNbO3 for SHG with 6.5 micrometers period, 10-mm length and 0.5-mm thickness has been successfully fabricated by applying an external electric field with an optimum high pulsec voltage generator. About 18-mW of cw 0.532 micrometers green light was obtained pumped by a 1.1 W of cw 1.064 μm Nd:YAG laser with end coupling, which corresponds to 1.6 percent power conversion efficiency. The SHG normalized conversion is about 1.5 percent cm-1W-1, which shows 79 percent of the ideal nonlinear coefficient.
