Query: Series solution to the laser-ion interaction in a Raman-type
  configuration   The Raman interaction of a trapped ultracold ion with two travelling wave
lasers is studied analytically with series solutions, in the absence of the
rotating wave approximation (RWA) and the restriction of both the Lamb-Dicke
limit and the weak excitation regime. The comparison is made between our
solutions and those under the RWA to demonstrate the validity region of the
RWA. As a practical example, the preparation of Schr\"odinger-cat states with
our solutions is proposed beyond the weak excitation regime.
