Poled polymers for frequency doubling of diode lasers

Abstract
We report on the design and characterization of methylmethacrylate copolymers with nonlinear optical 4‐alkoxy‐4’‐alkylsulfone stilbene sidechains, which are transparent down to 410 nm. A fairly stable, polar orientation has been obtained by means of electric field poling, resulting in a reasonably high nonlinearity (d33≤9 pm/V).
