Abstract
The optical characteristics of a commercial UV curable resin are investigat ed using nondegenerate four-wave mixing. The material assessed is an epoxy resin, DuPont Somos(TM) 7100. The holographic gratings were written at a wa velength of lambda = 351.1 nm for an irradiance range 0.5-3.0 W/cm(2) and r ead at lambda = 632.8 nm in order to assess the reactivity, curing speed, s hrinkage and resolution of the resin.
