Abstract

Simultaneous temporal and spatial resolution of the monochromatic vacuum ultraviolet emission from an excimer laser ablated YBa2Cu3O7 plasma has yielded quantitative information on the plasma generation and velocity. From the time resolved spectral data, plasma velocities were measured and found to be ∼2.3x106 cm/s. It was observed that vacuum ultraviolet emission from above the YBa2Cu3O7 surface does not occur until ˜20 ns after the beginning of the laser pulse. Energetic material continues to be ejected from the target for more than 100 ns after the end of the laser pulse.
