Optical measurement of heteronuclear cross-relaxation interactions in Tm:YAG

Résumé

We investigate cross-relaxation interactions between Tm and Al in Tm 3+ :YAG using two optical methods: spectral hole burning and stimulated echoes. These interactions lead to a substantial reduction in the hyperfine lifetime at magnetic fields that bring the Tm hyperfine transition into resonance with an Al transition. We develop models for the measured echo decay curves and hole-burning spectra near a resonance, which are used to show that the Tm-Al interaction has a resonance width of 12 ± 3 kHz and reduces the hyperfine lifetime at resonance to 0.5 ± 0.3 ms.
