We demonstrate that chirping the pump and stokes pulses in fractional stimulated Raman adiabatic passage can selectively create a maximally coherent superposition in a nearly degenerate four-level system, allowing high-resolution imaging.

A chirped-pulse control scheme for coherent anti-Stokes Raman spectroscopy, which is robust and selective in preparing a maximally coherent superposition of the ground electronic vibrational states, is presented with its application to remote detection.
