Paper Abstract

The Vanderbilt University free-electron laser (FEL) provides a continuously tunable ((lambda) equals 2 - 10 micrometer) source of pulsed IR radiation with a pulse structure unlike those of conventional lasers (a macropulse of 5 microseconds consisting of a train of 1 ps micropulses at a frequency of 3 GHz). A numerical hydrodynamic code at Lawrence Livermore National Laboratory, known as LASTIS3D, was used to model the ablation of tissue using the FEL. This study investigates the role of the FEL pulse structure by comparing the results from simulations using a time-averaged energy deposition and a pulsetrain energy deposition.
