We present a measurement of the dynamic scalar and tensor polarizabilities of the excited state |5d6s {sup 3}D{sub 1}> in atomic ytterbium. The polarizabilities were measured by analyzing the spectral lineshape of the 408-nm 6s{sup 2} {sup 1}S{sub 0{yields}}5d6s {sup 3}D{sub 1} transition driven by a standing wave of resonant light in the presence of static electric and magnetic fields. Due to the interaction of atoms with the standing wave, the lineshape has a characteristic polarizability-dependent distortion. A theoretical model was used to simulate the lineshape and determine a combination of the polarizabilities of the ground and excited states by fitting the model to experimental data. This combination was measured with a 13% uncertainty, only 3% of which was due to uncertainty in the simulation and fitting procedure. By comparing two different combinations of polarizabilities, the scalar and tensor polarizabilities of the state |5d6s {sup 3}D{sub 1}> were measured to be {alpha}{sub 0}({sup 3}D{sub 1})=0.009(21) Hz(V/cm){sup -2} and {alpha}{sub 2}({sup 3}D{sub 1})=-0.103(26) Hz(V/cm){sup -2}, respectively. We show that this technique can be applied to similar atomic systems.
