Abstract

Integrated laser ablation simulation code includes phase transition from liquid to neutral gas to partially ionized plasma, detail laser absorption processes, equation of state, hydrodynamics, and radiation transport, is developed to describe ablation phenomena with phase transition and properties of emission plasmas. For an application of this simulation code, we perform simulations on optimization of laser produced plasmas for extreme ultra violet (EUV) light sources. Because of very low laser intensities (from 10 ¹⁰ W/cm² to 10¹¹ W/cm² ) compared with that in laser fusion cases, it is necessary to include phase transition effects into ablation radiation hydrodynamics code.
