Efficient Cerenkov Second-Harmonic Generation in Crosslinked Poled Polymer Waveguides.

摘要

This paper presents frequency doubling results by Cerenkov radiation from stable poled polymer slab waveguides. For a 1064 nm Nd-YAG laser, the harmonic wavelength is away from the strong absorption region of the nonlinear optical polymer used. Green light was observed even when the laser was operating at a continuous wave 830 nm diode laser and a polymer with a larger nonlinear coefficient. The waveguide conversion efficiency for doubling of the diode laser was estimated to be 0.03 %/W with a total efficiency of 2.8 x 10-5 %/W. frequency doubling, waveguide, nonlinear optical polymer.
