  We experimentally study the role of the forcing on gravity-capillary wave
turbulence. Previous laboratory experiments using spatially localized forcing
(vibrating blades) have shown that the frequency power-law exponent of the
gravity wave spectrum depends on the forcing parameters. By horizontally
vibrating the whole container, we observe a spectrum exponent that does not
depend on the forcing parameters for both gravity and capillary regimes. This
spatially extended forcing leads to a gravity spectrum exponent in better
agreement with the theory than by using a spatially localized forcing. The role
of the vessel shape has been also studied. Finally, the wave spectrum is found
to scale linearly with the injected power for both regimes whatever the forcing
type used.
