I study the interaction of extremely intense light with matter. At lower intensities, this is the domain of nonlinear optics including such spectacular phenomena as white light continuum generation and filamentation. As somewhat higher intensities, I study laser damage (known in other contexts as laser surgery or laser machining). At the highest intensities, this is the domain of relativistic laser plasma physics.

I've kept this section for nostalgia. Following are just some pictures from my first lab located in Smith Hall and some of my first students.
The main laser system in my lab is based on Ti:Sapphire and produces 60 fs pulses with 1 mJ/pulse at a 1 kHz repetition rate. The pulses can be shaped using a LCD based pulse shaper. Below are two pictures of our laser system. It occupies a single 10' x 4' table. We also have numerous dye lasers for atomic excitation.
Here is what continuum generation looks like. Shown below is the result of sending our laser pulses through 1 mm of pure sapphire at a pulse energy around 2 uJ. The pulse energy increases slightly from left to right.
Here is continuum generation from a microstructure fiber using 1 nJ pump pulses (but lots of them).
