The power of the second harmonic irradiated by the cluster at the interaction with a femtosecond laser pulse is derived. The main contribution is produced by the relativistic oscillations of the electron cloud along the direction of the propagation of the laser pulse. The contribution into radiation

โฆ Synopsis
We consider one of the mechanisms for electron heating
inside large clusters irradiated by a relativistic femtosecond
laser pulse. This mechanism is related with the elastic reflection
of electrons from the cluster surface in the presence of laser
field, under the condition that cluster does not expand at the
leading edge of laser pulse. One obtains that the kinetic electron
energy is of the order of the electron ponderomotive energy both
in non-relativistic and relativistic cases.
