Abstract

Experiments are reported in which a high-density aluminum plasma was generated by a 10-picosecond KrF laser pulse. The amplified spontaneous emission (ASE) level of the prepulse was controlled by using a saturable dye. The electron density was estimated from the intensity ration of the Ly-alpha satellite components. It is found that ASE has to be suppressed to less than 10 exp 9 W/sq cm to create a high electron density plasma.
