Abstract
Visible green light has been observed by quasi-phase-matched second-ha rmonic generation from a periodic stack of free-standing poled polymer films, when pumped by a cw mode-locked near-infrared laser. The total thickness of the polymer film and phase-matching length was 300 mum w ith a conversion efficiency of 10(-6)-10(-5) depending on absorption. A polymer thin film processing technique is described for this applica tion that could make large area poled and stretched films with enhance d nonlinear optical susceptibilities.
