Abstract

Experimental observation of a laser-induced dipole–quadrupole collision between Sr and Ca is reported. The laser-induced collision cross section peaks at an applied photon energy equal to the energy defect of the initial and final states of the infinitely separated atoms. A cross section of 3 × 10⁻¹⁴ cm² was induced at a laser-power density of 7 × 10⁹ W/cm²; the linewidth was 20 cm⁻¹.
