Description: Self-generated magnetic fields up to 10 (exp 9) Gauss have been predicted in plasmas irradiated with ultra-intense laser light pulses with overdense plasmas. We find that the laser absorption can be significantly enhanced by the oscillation of electrons across these fields. There is then a very large Lorentz force, which can strongly accelerate electrons into the plasma and can lead to generation of harmonics in the reflected light. We also show that large magnetic fields can be significantly amplified to even larger values by the pressure of the light pulse. Potential applications are discussed.
