Mapping the Evolution of Optically-Generated Rotational Wavepackets in a Room Temperature Ensemble of D${}_2$

W. A. Bryan, E. M. L. English, J. McKenna +7

A coherent superposition of rotational states in D${}_2$ has been excited by nonresonant ultrafast (12 femtosecond) intense (2 $\times$ 10${}^{14}$ Wcm${}^{-2}$) 800 nm laser pulses lead…
