Echo Spectroscopy in multi-level quantum-mechanical rotors
arXiv:1808.06098 · doi:10.1103/PhysRevLett.121.234101
Abstract
The rotational echo response of molecules is found to strongly depend on the delay between the two ultrashort laser pulses, as opposed to two-level systems. We study this dependence experimentally and theoretically and show that by judicious control of the 2nd pulse intensity, 'rotational echo spectroscopy' in a multi-level molecular system becomes possible.
