Abstract
A laser method of and apparatus for providing a wide variety of laser wavelenghts wherein a pump source of laser radiation is sequentially Strokes-shifted in two separate cells each containing a different molecular or atomic Raman active gas, wherein each cell is optimized to produce primarily first-Stokes radiation as by variation of focal length parameters and/or gas pressure, filter means are provided at the output of the first cell to reject the pump laser radiation and to pass the first-Strokes radiation of the first cell and further filter means are provided at the output of the second cell to reject the first-Stokes radiation of the first cell and pass the first-Stokes radiation of the second cell to provide a desired output laser radiation.
