Abstract

Self-diffraction from laser-induced gratings is observed in a 13 μm-thick film of rhodamine B doped epoxy. The decay of the grating is measured to be 2.05 ns. Degenerate forward four-wave mixing in a guided geometry is observed by coupling out all beams after propagation over 1 mm. At 595 nm the third-order nonlinear susceptibility of the film is measured to be 1.5×10-19 m2 V-2.
