The spectrum of nonlinear inverse Compton radiation by the method of steepest descent.
Abstract
An attempt is made to show that considerable information on the power spectrum of an electron driven from rest by a strong linearly polarized electromagnetic plane wave can be gained relatively easily by an appropriate application of the method of steepest descents. The pertinent power spectrum is reexamined, the method of steepest descents is applied, and an asymptotic approximation to the adopted form of the power spectrum is derived in the case of high scattered harmonics. The results are compared with those obtained for a circularly polarized wave. Possible extensions of the method to other cases of astrophysical interest are discussed.
