Abstract

An optical detector for 29 cm-1 phonons in ruby is applied to study the interaction of the electronic states [MATH](2E) and 2 [MATH](2E) of the excited Cr3+ with the resonant 29 cm-1 phonons. For 1015 cm-3 excited Cr3+ the 29 cm-1 phonons can be trapped in the crystal due to resonant scattering. We found that the (spontaneous) decay time of the trapped phonons increased with increasing concentration of excited Cr3+ indicating a strong phonon bottleneck
