Abstract:
1. A laser system, comprising: a Raman fiber that is configured to act as a multiple wavelength Raman laser configured to receive a pulsed input beam from an input source and convert the input beam to an output beam having narrow band outputs at two or more frequencies including a first frequency v a nonlinear crystal, wherein an output of the Raman fiber is focused into the nonlinear crystal; and a pulsed laser input source optically coupled to the Raman fiber, wherein the pulsed input source is configured to provide the pulsed input beam, wherein the pulsed input beam is characterized by pulses having a rise time or fall time that is less than a pulse width for the pulses, wherein the pulses are configured such that a figure of merit (FOM) for the pulses is greater than about 60%, wherein the FOM is given by a percentage conversion of the input beam to a Raman wavelength corresponding to the first frequency when the power in a second Raman wavelength corresponding to the second frequency is about 2% of an input power of the input beam.
