Query: Doubly charged Higgs through photon photon collisions in 3-3-1 models   We study the production and signatures of doubly charged Higgs bosons in the
process \gamma\gamma H^{- -} H^{++} at the e^-e^+ International Linear Collider
and CERN Linear Collider, where the intermediate photons are given by the
Weizs[a\ddot]cker-Willians and laser backscattering distributions.
