We present a semiclassical treatment of two-photon laser-induced radiative collisions. We treat the two-photon-one-collision and two-photon-two-collision cases. We find a new intensity-induced collisional shift which makes the two-photon line shape highly sensitive to the intensity, and may make the line shape symmetric.
