We have observed laser-jitter-enhanced high-resolution spectra of three hyperfine states in the ground level (3H4) of Pr3+:Y2SiO5 using coherent population trapping and phase-correlated four-wave mixing. We have also observed optical Raman pulse excited two-photon spectral hole-burning. The observed high-resolution spectra are due to a laser-jitter-suppressed Raman coherence window in an inhomogeneously broadened solid system, and the observed two-photon spectral hole-burning has potential to increase data capacity in Raman excited optical memory (Opt. Lett. 22 (1997) 1849).
