Abstract

All-optical poling of crosslinkable polymer systems based on hexamethoxymethyl melamine (HMMM) and Disperse red 1 and 19 were experimentally investigated. Optimum poling condition of the two seeding beam intensity ratio, the temperature dependence, and the temporal stability of them were studied in details. It was found that the saturation SHG intensity decreased significantly with the increase of the sample temperature from 33 oC to 63 oC. From the respect of energy balance, the main factors of all-optical poling were analyzed, and a simple equation was first deduced to describe the requirement of realizing all optical poling..
