Supersymmetric theories with significant lepton flavor violation have \stackrel\ifmmode \else \~\fie and \stackrel\ifmmode \else \~\fi\ensuremathμ nearly degenerate. In this case, pair production of \stackrel\ifmmode \else \~\fie+\stackrel\ifmmode \else \~\fie^\ensuremath- and \stackrel\ifmmode \else \~\fi\ensuremathμ+\stackrel\ifmmode \else \~\fi\ensuremathμ^\ensuremath- at LEP II and at the Next Linear Collider (NLC) leads to the phenomenon of slepton oscillations, which is analogous to neutrino oscillations. The reach in \ensuremathΔm2 and sin22\ensuremathθ gives a probe of lepton flavor violation which is significantly more powerful than the current bounds from rare processes, such as \ensuremathμ\ensuremath→e\ensuremathγ. Polarizable e^\ensuremath- beams and the e^\ensuremath-e^\ensuremath- mode at the NLC are found to be promising options.
