Numerical solutions of the time-dependent Schroedinger equation have been obtained for one and two-electron quantum proton "wires": Hn,n=2-5.These exact simulations demonstrate the existence of a new molecular-strong field phenomenon not encountered in single atoms under similar conditions: Charge Resonance Enhanced Ionization-CREI, and enhanced high order Harmonic Generation into the VUV-X_Ray region. Interpretation of these unusual nonlinear non-perturbative optical phenomena will be shown to be possible using simple classical plasma physics concepts. Finally an exact non-Born-Oppenheimer calculation has been realized for the H2+ system allowing for the calculation of Above Threshold IOnization,ATI, electron and nuclear Coulomb explosion spectra simultaneously. These new results will be shown to lead to a new molecular imaging technique: Laser Induced Coulomb Explosion Imagery-LICEI. Possible early experimental results form PBCorkum,s NRC(Ottawa) laboratory will be shown.
