Paper Abstract

Resonance-enhanced anti-stokes of stimulated four photon mixing is demonstrated for the first time in an Er3+ doped silica fiber under the excitation of a 1064 nm laser. The enhancement of 977 nm anti-stokes of stimulated four-photon mixing by the excited state 4I11/2 of Er3+ has been observed. After the fiber being prepared for efficient SHG, the spectra of stokes and anti-stokes stimulated four-photon mixing were measured again and found to have shifted 2 nm, respectively. We attribute this phenomenon to photo induced refractive-index changes in the fiber: one is caused by the short wavelength light absorptions of GeO, and the other is by the change of intensity-dependent Er3+ population in excited states.
