Abstract

Heating of high energy density plasmas using extreme ultra-violet (EUV) and x-ray lasers is examined. Our modeling studies show that solid carbon and iron can be heated by focused X-ray laser pulses of irradiance 10(17) Wcm(-2), duration 100 fs so that after a picosecond or so equilibration, LTE plasmas of temperatures up to 400 eV are produced in a uniform solid density of thickness close to one micron. Solid target heating experiments can also be carried out with laboratory based EUV lasers, but the temperatures achieved are <20 eV. The equilibrium temperature reached with EUV and X-ray laser heating is strongly dependent on the photon energy, while the focused irradiance determines the thickness of heated material.
