The excitation of large amplitude nonlinear waves is achieved via parametric autoresonance of Faraday

waves. We experimentally demonstrate that phase locking to low amplitude driving can generate

persistent high-amplitude growth of nonlinear waves in a dissipative system. The experiments presented

are in excellent agreement with theory.
