  Lepton-flavor-violating decays of the type L->l gamma gamma (mu->e gamma
gamma, tau->e gamma gamma, and tau->mu gamma gamma) are proposed as new probes
of R-parity-violating supersymmetry. Non-penguin diagrams with a sneutrino that
decays into two photons via a triangle graph might trigger such decays even in
the absence of the corresponding radiative decays into one photon only, e.g.
mu->e gamma. Thus, processes of the type L->l gamma gamma may provide an
independent probe of new flavor physics.
