ABSTRACT:
A two-cell Raman converter for generating a relatively large number of Stokes shifted waves from an input laser pump beam. A first lens focuses the pump beam into the first cell, whose output is recollimated and focused by second and third lenses into the second cell. The second cell output is recollimated by a recollimating lens to provide the final output. Each Raman cell employs stimuated rotational Raman scattering and Raman media at low pressures optimized to achieve maximum conversion into Stokes lines.
