Recoil and Gravitational Effects of Electrons in Plasmas within Very Intense Laser Radiation
The relativistic oscillation energy εosc of electrons in laser fields of an intensity I which follows a square root law is understandable for black body radiation of very high temperature T, since εosc~T.
The subrelativistic behaviour εosc~T3 is a kind of Debye T3 — law with a Debye energy of mc2. In analogy to Einstein’s lav of recoil for the emitters and absorbers with kT/2 energy per degree of freedom, we find the same for εosc, if the reciprocal fine structure constant were 142.17. The correction due to neglect of self damping is in the right direction. The relativistic change of the mass of the electrons is compared with the energy density of the laser field. Near the cut-off density, a generation of a gravitational wave of the laser frequency should be possible.
