ABSTRACT:

Major technological advances have been made in the last decade in pulsed
lasers.  Lasers with tens of femtosecond pulse duration have been
commercialized in relatively ruggedized single enclosure systems capable of
producing watts of average power.  These energy densities on the order of
GW peak powers can trigger various linear and non-linear processes, leading
to self-guided propagation and dense plasma creation in air and condensed
media.  The free-electrons in these plasma regions have been shown to reach
densities up to 1016 /cm3 in sea-level atmospheric conditions and stable
plasma filaments have been created extending over 100’s of meters.

Supporting applications of these lasers with predictive models is a
difficult task as computational propagation of high power, short pulse
lasers with arbitrary beam profiles is highly complex.  These types of
models require high resolution of a 3-dimensional volume propagated through
time and include broadband non-linear effects of the media with which they
are interacting.  Add in turbulence and statistical beam effects and the
system can quickly become computationally unwieldy. This talk will describe
recent work in simulating the Ultra Short Pulse Laser propagation and the
resulting non-linear effects, including the creation of plasma as well as
various experimental laboratory results.
