Abstract
We present results on the evolution of jets (electrons-positrons and photons) formed in colliding two ultraintense laser pulses with varying frequencies and amplitudes. We focus on the nonlinear dynamics of the seeded electrons in the superposition of the two counterpropagating laser pulses and its implications for the experimentally measurable properties of jets, e.g., angular spectra and widths of the emitted jets, by changing the intensity and frequency of the two colliding laser pulses. We verify our analytical results by doing both Monte Carlo and two-dimensional particle-in-cell simulations.
