Stimulated Raman scattering, stimulated Raman cascade and the transition from Raman cascade into photon condensation, induced by a linearly‐polarized intense laser interacting with low‐density uniform plasmas, are studied by particle simulations. It is found that, at appropriate laser amplitude and plasma condition, a large amplitude relativistic EM soliton forms due to the strong photon condensation. The standing, backward‐ and forward‐accelerated ultra‐relativistic electromagnetic solitons induced by intense laser pulses are observed. In addition to the inhomogeneity of the plasma density the acceleration of solitons depends upon, both, the laser intensity and the plasma length. The frequency of solitons is about half of the unperturbed electron plasma frequency, while the transverse electric, magnetic and electrostatic field have half‐, one‐ and one‐cycle spatial structure, respectively.
