Ultrafast Impulse Studies to Determine Momentum Coupling Coefficients in Metallic Systems

In collaboration with the Johns Hopkins Applied Physics Laboratory, momentum coupling coefficients are being measured for ultrafast excitation of various metallic systems.  Current measurements (approaching fluxes of 1 TW/mm2) have quantified momentum transfer under vacuum as well as with under cover gases. These types of studies are critical for applications ranging from microsatellite propulsion and attitude control to ultrafast trimming operations. Current efforts are directed towards assessing the effects of thin organic overlayers on material removal processes and the related implications for impulse control.

We investigate the related energy transfer mechanisms in organic layer/substrate systems.
