Abstract
The optically induced phonon distribution in Cr3+-doped germanate glas s is investigated after pulsed laser excitation. Via the anti-Stokes s pectrum a nonequilibrium phonon distribution is observed, which is cha racterized by a marked overpopulation at higher frequencies, and persi sts over several milliseconds.
