| Abstract | We report on the observation of slow light induced by transient spectral hole-burning in a solidthat is based on excited-state population storage. Experiments were conducted in the R1-line (2E-4A2 transition) of a 2.3 mm thick pink ruby (Al2O3:Cr(III) 130 ppm). Importantlythe pulse delay can be controlled by the application of a low external magnetic field B||c≪9 mT and delays of up to 11 ns with minimal pulse distortion are observed for ∼55 ns Gaussian pulses. The delay corresponds to a group velocity value of ∼c/1400. The experiment is very well modelled by linear spectral filter theory and the results indicate the possibility of using transient hole-burning based slow light experiments as a spectroscopic technique. |
