摘要
A laser system comprising (i) a pulsed light source (102) generating a pulsed light having an optical spectrum centered at a source wavelength, (ii) a Raman conversion fiber (106) coupled the pulsed light source, wherein the pulsed light traverses the nonlinear Raman conversion fiber and is converted by a cascaded Stimulated Raman Scattering process into a first pulsed light output corresponding to last Stokes order and having an optical spectrum centered at a first output wavelength which is longer than the source wavelength, and (iii) a harmonic generator (110) operatively coupled to said a Raman conversion fiber to accept the first pulsed light output order and to convert it to longer optical frequency such that said harmonic generator producing light output in the final output wavelength situated in the 150-775 nm range.
