High gradient laser plasma is formed by focused KrF laser pulses (248.3 nm, 450 fs, 1013 W/cm2) on liquids (water, styrene) and solids (silicon, aluminum, and polyimide). The hydrodynamic expansion of the plasma was studied by measuring the blue Dopp

Degradation of the same hydrogenated amorphous silicon (a:Si:H) samples with short laser pulses (30 ns) and steady bandgap light (CW) reveals that the kinetics is different for pulses and CW. For pulse degradation the kinetics depends on doping. Part
