| Research Abstract |
Electronic structures, photoabsorption coefficients and collisional relaxation rates in laser-produced warm dense matter have been analyzed with quantum-statistical theories. Absorption saturation and nonlinear transmission of a vacuum ultra-violet laser pulse through solid lithium have been demonstrated for an intensity greater than 1013W/cm2. We have also developed a method based on energy-band calculations to evaluate photoabsorption coefficients of simple metals for photon energies from ultra-violet to x-ray regions.
