absorption. Specifically, when a mode-locked laser beam is focused to a small spot size, the high intensity at the focal spot causes the electrons to be excited by simultaneous absorption of multiple low-energy photons. Material is ejected as atoms or small molecular fragments. Multiphoton absorption
