Upconversion of He-Ne Laser Light in Xanthene Dye-doped Polymer Waveguides

Samoc, Anna; Samoc, Marek; Luther-Davies, Barry


We report on generation of yellow light emission (peak intensity at 577 nm) from a low power red He-Ne laser beam (1 mW, 632.8 nm) propagating in dye-doped planar polymer waveguides. Upconversion of He-Ne light (higher energy photons created by lower energy photons) was observed in planar slab waveguides made of poly(N-vinylpyrrolidone) (PVP) doped with Phloxine B. The films viewed from the side show a characteristic streak of yellow light. Monitoring it with a CCD camera we find that logarithm...[Show more]
