Picosecond laser plasma creation in the presence of high electrostatic field on the surface of metals
Abstract
Plasma was created by picosecond Nd-laser pulses on metal surfaces. In contrast to usual experiments the plasma was created in the presence of strong outer electrostatic field. In addition to strong ion and electron emission, very intense X-ray radiation was also observed, the intensity and energy of which depended to a very great extent both on the value and the polarity of the outer electrostatic field.
