Abstract
Electrons injected into a high-intensity laser focus by tunneling ionization quickly escape as a result of the strong ponderomotive force. This limits the probability of observing harmonic radiation from free electrons oscillating in the field1 and other nonlinear effects. Two-dimension (radial) optical confining schemes have been proposed to increase the lifetime of the electron in the intense field.2,3 These do not confine the electrons in the direction of the laser propagation, which limits their effectiveness. In intense fields the electrons have significant momentum in this direction.4 To our knowledge, neither of these schemes has been demonstrated.
