    The authors report on the implementation of phase sensitivity into Brillouin light scattering spectroscopy from propagating spin-wave packets. In order to access phase information, interference between the light inelastically scattered by the spin-wave and a frequency shifted coherent reference beam is used. This approach allows for access to quantities such as the space- and time-resolved phase profile and the wave front of spin-wave packets and beams. The authors apply the developed method to investigations of the phase profiles of linear and nonlinear (soliton) spin-wave pulses. In particular, the constant phase profile characteristics for an envelope spin-wave soliton are demonstrated. (c) 2006 American Institute of Physics.
