  We obtain a class of elliptic wave solutions of coupled nonlinear Helmholtz
(CNLH) equations describing nonparaxial ultra-broad beam propagation in
nonlinear Kerr-like media, in terms of the Jacobi elliptic functions and also
discuss their limiting forms (hyperbolic solutions). Especially, we show the
existence of non-trivial solitary wave profiles in the CNLH system. The effect
of nonparaxiality on the speed, pulse width and amplitude of the nonlinear
waves is analysed in detail. Particularly a mechanism for tuning the speed by
altering the nonparaxial parameter is proposed. We also identify a novel
phase-unlocking behaviour due to the presence of nonparaxial parameter.
