It is pointed out that ''tunnel'' mode locking is possible in lasers with a dispersive medium in the resonator because of the tunnel transmission of subpicosecond (femtosecond) light pulses by the dispersing medium provided it occupies a characteristic tunnel length along the resonator axis. A theory of tunnel mode locking is developed for the Kerr mode-locking nonlinearity. Equations are derived for the dynamics of changes in the phases of the generated modes. The locking band is determined for three modes and frequency modulation of these modes outside the band is predicted. A locking band is also estimated for an arbitrary number of generated modes and this is used to demonstrate the possibility of generating light pulses of duration down to 3 x 10/sup -14/ sec.
