A gold nanaparticle doped core fiber of core-diameter 2microns and 13cm length was
prepared. The power dependence of the polarization state of the output light was measured.
The maximum change of the azimuth and the ellipticity angles for 192 fs pulse width and 5.1 W peak power were 28 degrees and 31 degrees, respectively.
