Full-dimensional quantum simulations of dissociative ionization driven by strong orthogonal laser fields—including equal-frequency orthogonal components and - and -nm two-color fields—strongly modify fragmentation dynamics. Notably, a high-energy peak in the proton kinetic-energy-release spectrum at approximately eV is identified, absent from single-color calculations.
