Abstract : A high-powered, continuous beam laser system is examined in terms of the physical conditions which exist if the laser beam is brought to a diffraction-limited, real focus in a moderate vacuum environment. Ionization of the gas at the focus by multiphoton processes is extensive, but it is shown that neither reflection of the beam by the plasma at the focus nor absorption by ionization is sufficient to disrupt propagation of the beam through the focus.
