Query: Detecting an Intermediate Mass Charged Higgs at $\gamma \gamma$
  Colliders   The detection of an intermediate mass charged Higgs boson at $\gamgam$
colliders via the modes $\gamgam \to H^+ H^- \to \nu \tau^+ \bar{\nu} \tau^-,~
c \bar{s} \bar{c} s,~$ and $ \nu \tau^+ \bar{c}s + c \bar{s} \bar{\nu} \tau^-$
is considered. $W^+ W^-$ boson pair production is the dominant background for
these modes. The three modes may be used in a complementary fashion to detect a
charged Higgs boson. The mixed leptonic-hadronic mode may be used to determine
the charged Higgs mass by reconstructing the invariant hadronic mass. The
sensitivity of Br$(H^+ \rightarrow c\bar s,\,\nu \tau^+)$ on the discovery
limit of the charged Higgs boson is also discussed.
