Recent Development of Ultrafast Thermoelasticity.

Ultrafast deformation is caused by intense heating of femtosecond lasers that involve ultrafast energy exchange between electrons and metal lattices in the femto- to picosecond domain. This work outlines unique features including interactions between T-waves and stress waves in the femtosecond domain and the hot-electron blast that can destroy cold lattices before they become thermally excited. Dominating groups are identified to characterize the ultrafast thermomechanical response. [ABSTRACT FROM AUTHOR]
