The ultraslow light propagation, and stopped or trapped light storage in optically dense crystals of Pr doped Y2SiO5 were reported. Light speeds as low as 45m/s were observed in the solid, corresponding to a group delay of 66οsecond. Reduction in group velocity was accomplished using a sharp spectral feature produced by resonant Raman excitation of a ground state spin coherence. The observations have applications in low-intensity nonlinear optics, quantum information processing and quantum information storage.
