  We studied the production and signatures of doubly charged Higgs bosons in
the process $\gamma e^- \rightarrow H^{--}E^+$, where $E^+$ is a heavy lepton,
at the $e^-e^+$ International Linear Collider (ILC) and CERN Linear Collider
(CLIC). The intermediate photons are given by the Weizs$\ddot{a}$cker-Williams
and laser backscattering distributions. We found that significant signatures
are obtained by bremsstrahlung and backward Comptom scattering of laser. A
clear signal can be obtained for doubly charged Higgs bosons, doubly charged
gauge bosons and heavy leptons.
