Abstract
In one embodiment, the instant invention provides a method that includes: outputting a first laser beam having: a beam quality factor (M2) between 1 and 5, and a spectral width of less than 0.15 nm, where the outputting is performed by a laser generating component that includes a alexandrite laser oscillator; converting the first laser beam through a first Raman cell to produce a second laser beam, where the first Raman cell is filled with a first gas; and converting the second laser beam through a second Raman cell to produce a final laser beam, where the second Raman cell is filled with a second gas and is operationally positioned after the first Raman cell, where the first gas and the second gas are different gasses, and where the final laser beam having: a second energy of at least 1 mJ, and at least one wavelength longer than 2.5 micron.
