Laser-induced gratings in the gas phase excited by Raman-active transitions.

Optics letters

Kozlov DN, Bombach R, Hemmerling B, Hubschmid W.
PMID: 18183098
Opt Lett. 1997 Jan 01;22(1):46-8. doi: 10.1364/ol.22.000046.

We report on a new time-resolved coherent Raman technique that is based on the generation of thermal gratings following a population change among molecular levels that is induced by stimulated Raman pumping. This is achieved by use of spatially...

We demonstrate the mixing of rotational states in the ground electronic state using microwave radiation to enhance optical cycling in the molecule yttrium (II) monoxide (YO). This mixing technique is used in conjunction with a frequency modulated and chirped...

Robust Coherent Transport of Light in Multilevel Hot Atomic Vapors.

Physical review letters

PMID: 31144888
Phys Rev Lett. 2019 May 10;122(18):183203. doi: 10.1103/PhysRevLett.122.183203.

Using a model system, we demonstrate both experimentally and theoretically that coherent scattering of light can be robust in hot atomic vapors despite a significant Doppler effect. By operating in a linear regime of far-detuned light scattering, we also...
