  We present the research of ocean surface wind waves excitation in
non-homogeneous situations, on the example of deep water strait in presence of
the constant wind, blowing perpendicular to the coastal line. The used
statistical wave model is based on Hasselmann equation with high-wavenumbers
wave-breaking dissipation, exact nonlinear four-waves interaction and ZRP wind
input term. At the first stage, the waves propagate in the wind direction in a
step-like moving front manner, which is the combination of self-similar
fetch-limited and duration-limited solutions of Hasselmann equation. The second
stage begins further, when sufficient amount of wave energy is concentrated at
the incoming waves shore line. Beginning with that time, the nonlinear wave
interactions start formation of the wave groups, propagating across and against
the wind. Despite the absence of long-wave dissipation, the system
asymptotically evolves into complicated quasi-stationary state, comprising of
the self-similar ``wind sea'' in the wind direction, and quasi-monochromatic
waves, radiated close to orthogonally with respect to the wind, while slightly
tilting counter the wind direction with the angle increasing toward the wave
turbulence origination shore line, and reaching $15^{\circ}$ close to it. The
total wave energy in the asymptotic state surpasses the wave sea energy
propagating along the wind by two times due to the presence of quasi-orthogonal
and counter the wind wave fields. The very similar turbulence structure was
previously observed experimentally, this paper presents theoretical explanation
of these results. It is suggested to name this laser-like radiation phenomenon
by Nonlinear Ocean Waves Amplifier, simplified to the abbreviation NOWA.
