We study atomic, molecular, and optical physics. Our current research effort includes Stark spectroscopy of two electron atoms and the underlying connection to classical dynamics, super continuum generation, the control of continuum generation, population transfer via coherent control, and the use of genetic algorithms in coherent control. We also spend a fair amount of time developing laser systems.
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).
