Abstract: Two-photon emission of an electron in an electromagnetic plane wave of vanishing frequency is calculated. The unpolarized probability is split into a two-step process, which is shown to be exactly equal to an integration over polarized subprocesses, and a one-step process, which is found to be dominant over the formation length. The assumptions of neglecting spin and simultaneous emission, commonly used in numerical simulations, are discussed in light of these results.
