Time-resolved and time-integrated measurements were made of the plasma produced by a Q-switched laser beam focused on the surface of a metallic solid. Photographic, spectroscopic and charged particle emission data were taken on a nanosecond basis using a one megawatt peak power Nd laser. Experimental results indicate a plume velocity of 2.5cmmicrosec., a plasma temperature of 40,000K and an electron density of 5 x 10 to the 17th powercc. It was also found that it requires 6-10 nanoseconds for a laser beam to penetrate a thin metal foil. Author
