Abstract: (1213 Views)
In this article, the interaction of KrF laser with deuterium is investigated. in sub-relativistic intensities, the collisional absorption is dominant. Therefore, the collision frequency of electron-ion has important role in the energy absorption. At high temperatures, the classical impact parameter is longer than Broglie wavelength. as a consequence, the quantum correction appears in the frequency collisions and the electrical conductivity. Considering the plasma temperature greater than 36ev and the quantum correction in GENUINE two-fluid hydrodynamic code, the electron heating in plasma are studied. It is found that due to the quantum correction, the collision frequency and the electrical conductivity are modified. So the electron heating considerably increases up to the maximum temperature of 3.2×107K which is bigger than about twice the classical case. Also, the temperature stays almost constant for more than 600 fs of interaction time.
