We study the potential of the $\gamma \gamma$ option of future high-energy linear $e^{+}{e}^{-}$ colliders to search for excited electrons with spin-$1/2$. We calculate single production cross sections and give the angular distributions and $f-m*$ contour plots for $\sqrt{s}=0.5\mathrm{TeV}$ and $\sqrt{s}=3\mathrm{TeV}$ both using the standard (tree-level) couplings and anomal couplings.
