SUMMARY:Damage Control: Using Coherent Phonon Oscillations to Control Material Damage -- Carl Liebig
DESCRIPTION:Departmental Colloquium. Dr. Bill Dennis will be hosting Dr. Carl Liebig of Purdue University Department of Mechanical Engineering this week. The talk is entitled, "Damage Control: Using Coherent Phonon Oscillations to Control Material Damage."With an optical pulse duration shorter than the time required for heat generation in
materials, femtosecond laser pulses have advantages over traditional nanosecond laser systems
in their ability to maximize the amount of intended damage and minimize collateral damage.
The broadband nature of femtosecond laser pulses also allows them to be customized to control
physical phenomena such as coherent phonon oscillations and non-thermal melting that can
contribute to the damage process. This talk will introduce femtosecond pulse shaping, show
how the shaped pulses can be used to control coherent phonon oscillations and discuss how to
control the the material damage by manipulating the coherent phonon amplitude.
