PULSED CASCADED RAMAN LASER

A pulsed cascaded Raman laser ( 10 ) includes a pulsed light source ( 102 ) for generating a pulsed light ( 104 ) having an optical spectrum centered at a source wavelength. A non-linear Raman conversion fiber ( 106 ) is coupled to the pulsed light source ( 102 ). The pulsed light ( 104 ) traverses...

Beschreibung
Zusammenfassung:	A pulsed cascaded Raman laser ( 10 ) includes a pulsed light source ( 102 ) for generating a pulsed light ( 104 ) having an optical spectrum centered at a source wavelength. A non-linear Raman conversion fiber ( 106 ) is coupled to the pulsed light source ( 102 ). The pulsed light ( 104 ) traverses the nonlinear Raman conversion fiber ( 106 ) and the source power at the source wavelength is converted to a power output of an output signal ( 108 ) having an output wavelength longer than the source wavelength by a cascaded Stimulated Raman Scattering process, such that most of the source power is converted to the power of the last Stokes order in a single pass through the non-linear Raman conversion fiber ( 106 ).
