Abstract :
We have extended the physics of the one-dimensional radiation hydrodynamics simulation code HYADES to include
processes important for studying laser–matter interaction with dielectrics and metals in the eV and sub-eV electron
temperature range. Ultra-short laser pulses USLP.are advantageous in many material processing situations where most of
the absorbed laser energy appears in mass motion, and little appears as thermal energy. Major additions to the code include
1. the transport, reflection and absorption of laser light, 2. thermal energy transport and improved shockwave physics, and
3. improved models for the equation of state EOS., strength of materials, and fracture. Examples from material processing
and plasma generation were chosen for simulation. Our numerical simulations include the effects of radiation transport,
hydrodynamic expansion and shockwave phenomena. q1998 Elsevier Science B.V.
