Abstract

A fast (tau/response &lt;90 fs) free-electron spin-flipping frequency-degenerate nonlinearity with a significant value of |chi(3)xxyy(w,w,w,-w) chi(3)xyyx(w,w,w,-w)| ~ 10^-8 esu has been observed in bulk gold at 1260 nm by use of a new pump-probe polarization-sensitive technique.  [where w=omega]<br/
