Note on Inverse Bremsstrahlung in a Strong Electromagnetic Field.

PDF Version Also Available for Download.

Description

The collisional energy loss of an electron undergoing forced oscillation in an electromagnetic field behaves quite differently in the low and high intensity limits. In the case where the thermal velocity v{sub t} is much larger than v{sub 0} = eE{sub 0}m{omega} the rate at which the electron transfers energy to the random motion of the medium is proportional to v{sub 0}{sup 2}. It is shown that in the case of an electromagnetic field v{sub 0} >> v{sub t} the rate of transfer is much slower, and actually decreases with the strength of the field.
