Laser absorption and ion acceleration under tight-focusing conditions
Original language description
One of the most promising techniques to enhance the focused laser intensities is to use ellipsoidal plasma mirrors to tightly focus a laser beam. This technique has been successfully employed to obtain sub-μm spot size in which case one may expect an order of magnitude increase in focused intensity in comparison with a typical spot size of about 3-4 microns obtained using f/3 off axis parabolic mirror. Not only the higher intensity, but also an extremely strong radial ponderomotive force and a strong longitudinal electric field compo- nent affect the trajectories of electrons in the focal spot area. They have a significant effect on the absorption process and parameters of hot electrons and in turn on ion acceleration from the surface of a thin foil targets in the TNSA process.
