We experimentally and theoretically investigate the coherent response of [Formula Presented] ions in yttrium aluminum garnet (YAG). Working on the [Formula Presented] transition we observe optical nutation signals that exhibit multiple distinct Fourier components having polarization-dependent frequencies and weights. This phenomenon is caused by the presence of six different transition-dipole moment orientations of [Formula Presented] ions in YAG and a resultant dependence of ion-field coupling on field-propagation direction and polarization. Experimental data shown are in excellent agreement with simulation results based on numerical integration of the Maxwell-Bloch equations.
