Copyrighted Software: (2 copyrighted software packages)
SLIM (Simulation of Laser Interaction with Materials, 36,000 coded lines, 1992) software. This first-of-its-kind software is being used by more than 50 R&D groups (IBM, LANL, ORNL, etc.) in the world. This software calculates the transient thermal induced laser effects like melting, crystallization and ablation of materials. Two new versions (one based on DOS C++ and the other on Windows platform) have been developed.

Femto-SLIM (32,000 coded lines, 1995, Tech: Partner: Univ. of Michigan.) New software to model ultrafast laser -solid interactions by taking into account the electron-phonon energy transfer. Due to nature of the short pulses, a two temperature (electron temperature and lattice temperature) simulation model has been developed to model the short pulse effects.This software is being jointly owned by the University of Florida and the University of Michigan and is done in active collaboration with the NSF Science and Technology Center for Ultrafast Optical Sciences (CUOS) at the University of Michigan.
