  The charged Higgs pair production via photon-photon collisions is
investigated in the framework of two Higgs doublet model (2HDM), taking into
account a full set of one-loop-level scattering amplitudes, i.e., including
electroweak (EW) corrections together with soft and hard QED radiation. The
numerical evaluation is carried out for three different scenarios, so-called
non-alignment, low-$m_H$ and short-cascade, defined in the presence of the
up-to-date experimental constraints and consistent with theoretical constraints
as well. The total cross sections of $\gamma\gamma \rightarrow H^{-}H^{+}$ are
scanned over the plane ($m_{\phi^0},\sqrt{s}$), where $\phi^0$ is $h^0$ for
low-$m_{H^0}$ scenario and $H^0$ for other two scenarios. The regions of the
parameter space in which the production rates are sufficiently large are
highlighted for each scenario. The production rates in different polarization
collision modes of initial beams are also discussed. It can be enhanced up to
two-times by oppositely polarized photons at high energies and right-handed
polarized photons at low energies. Furthermore, decay channels of the charged
Higgs boson are examined for each scenario. It is observed that the one-loop EW
corrections, i.e., the virtual plus real radiation corrections, reduce the
tree-level cross sections and the relative correction is typically in the range
of $-10\%$ to $-30\%$, depending on model parameters.
