Two-color resonant four-wave mixing spectroscopy: New perspectives for direct studies of collisional state-to-state transfer

Chen, X.; Settersten, T.B.; Radi, P.P.; Kouzov, A.P.

The two-color resonant four-wave mixing (TC-RFWM) is advertised as a unique spectroscopic device enabling one to directly measure the collisional state-to-state transfer characteristics (rates and correlation times). In contrast to the laser-induced fluorescence, these characteristics are phase-sensitive and open wider opportunities to study the rotational relaxation processes. Further perspectives are offered by the recently recorded collision-induced picosecond TC-RFWM signals of OH. Their quantitative interpretation is now under development. © 2008 American Institute of Physics.
