title: Measurement of the hyperfine structure of Pr(3:):YAG by quantum-beat free-induction decay, hole burning, and optically detected nuclear quadrupole resonance.
abstract: The hyperfine splitting of the ground state and the lowest electronic component of the (1)D(2) excited state have been measured for Pr(3+) in YAG. We show that a particularly simple and powerful technique is the production of sublevel coherence by short-pulse (impact) excitation, which is detected by coherent forward scattering of a weak probe beam and Fourier transformation of the resulting quantum-beat signal. This yielded excited-state splittings of 6.49 and 8.29 MHz. The ground state shows large pseudoquadrupole splittings of 33.4 and 41.6 MHz, which were obtained by optically detected nuclear quadrupole resonance.
