The differences in the plasma waves generated either in the laser wake plasmon conceptl or with long laser pulse accelerator concepts are pointed out. An emphasis is also given to the concept that uses the stimulated forward Raman scattering effect by seeding a second wave, such as in the beat wave concept but with a much smaller amplitude. In various cases, stochastic heating is observed. Conditions for an efficient accelerator and considerations on the effective accelerating gradient are also given.
