In this work, we develop a self-consistent, nonperturbative Hamiltonian formulation for the cyclotron-resonance laser accelerator. The formalism takes into account wave dispersion and frequency mismatch, enabling one to show how the mismatch can be used to remove some of the energization limits imposed by dispersion.
