MULTIPLE WAVELENGTH RAMAN LASER

摘要

A pulsed laser system may include a Raman fiber that is configured to act as multiple wavelength Raman laser. The fiber is 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 first and second frequencies v1 and v2.

1. A laser system, comprising:
an optical fiber configured to receive a pulsed input beam from an input source and convert the input beam to an output beam having outputs at two or more frequencies including a first frequency v1 and a second frequency v2; a nonlinear material, wherein an output of the optical fiber is focused into the nonlinear material; and a pulsed laser input source optically coupled to the optical fiber, wherein the pulsed input source is configured to provide the pulsed input beam, wherein the pulsed input beam is characterized by one or more pulses configured such that a figure of merit (FOM) for the one or more pulses is greater than about 60%, wherein the FOM is given by a percentage conversion of the input beam to the first frequency when the power at the second frequency is about 2% of an input power of the input beam.
