  We discuss the production of the doubly charged leptons in future linear
electron positron colliders, such as the International Linear Collider and
Compact Linear Collider. Such states are introduced in extended weak-isospin
multiplets by composite models. We discuss the production cross section of
$e^-\gamma\rightarrow L^{--}W^{+}$ and carry out analyses for hadronic,
semi-leptonic and pure leptonic channels based on the full simulation
performance of the Silicon Detector. The 3- and 5-sigma statistical
significance exclusion curves are provided in the model parameter space. It is
found that the hadronic channel could offer the most possible detectable
signature.
