ABSTRACT:
A system and method for converting a pulsed beam of irradiation from a laser operating at a first wavelength to a pulsed beam of irradiation at a second, Stokes, wavelength. The system includes two Raman cells filled with the same Raman-active gas. The second cell receives a backward-propagating Stokes pulse beam from the first Raman cell, with the backward-propagating Stokes pulsed beam entering the second Raman cell in a direction opposite to the direction of travel of the incoming laser pulses at the first wavelength. The second Raman cell generates a high intensity output pulsed beam at the second, Stokes, wavelength. The system can produce a high intensity eye-safe pulsed beam.
