The semiclassical formula for the quantum propagator in the coherent
state representation $\langle \mathbf{z}'' | e^{-i\hat{H}T/\hbar} |
\mathbf{z}'\rangle$ is not free from the problem of caustics. These
are singular points along the complex classical trajectories
specified by $\mathbf{z}'$, $\mathbf{z}''$ and $T$ where the usual
quadratic approximation fails, leading to divergences in the
semiclassical formula. In this paper we derive third order
approximations for this propagator that remain finite in the
vicinity of caustics. We use Maslov's method and the dual
representation proposed in Phys.~Rev.~Lett.~{\bf 95}, 050405 (2005)
to derive uniform, regular and transitional semiclassical
approximations for coherent state propagator in systems with two
degrees of freedom.
