174Yb 3P1 level relaxation found via weak magnetic field dependence of collision-induced stimulated photon echo
Abstract
Collision-induced stimulated photon echo generated at transition was analyzed theoretically and investigated experimentally in the gaseous mixture of ytterbium vapour diluted with a large amount of buffer gas xenon in the presence of a weak longitudinal magnetic field. The inter-combination transition of 174Yb (6s2) 1S(6s6p) 3P1 was used; all experimental parameters were carefully controlled for their correspondence to the broad spectral line conditions. The curve representing the collision-induced stimulated photon echo variations versus a weak magnetic field strength showed very good agreement with the corresponding theoretical curve; this agreement permitted getting the decay rates for 174Yb level 3P1 orientation and alignment in collisions with Xe.
