Raman generation by phased and antiphased molecular states

We use molecular deuterium and two driving lasers to demonstrate collinear generation of mutually coherent equidistant sidebands, covering 50 000 cm(-1) of spectral bandwidth and ranging front 2.93 mu m to 195 nm in wavelength. The essential idea is the adiabatic preparation of a single, highly coherent (\rho(ab)\ = 0.33) molecular eigenstate.
