Abstract

We perform hole burning with a low-drift stabilized laser within the zero phonon line of the 4f-5d transition in Ce3+:Y2SiO5 at 2 K. The narrowest spectral holes appear for small applied magnetic fields and are 6±4 MHz wide (FWHM). This puts an upper bound on the homogeneous linewidth of the transition to 3±2 MHz, which is close to lifetime limited. The spin level relaxation time is measured to 72±21 ms with a magnetic field of 10 mT. A slow permanent hole burning mechanism is observed. If the excitation frequency is not changed the fluorescence intensity is reduced by more than 50% after a couple of minutes of continuous excitation. The spectral hole created by the permanent hole burning has a width in the tens of MHz range, which... (More)

If the excitation frequency is not changed the fluorescence intensity is reduced by more than 50% after a couple of minutes of continuous excitation. The spectral hole created by the permanent hole burning has a width in the tens of MHz range, which indicates that a trapping mechanism occurs via the 5d state.
