Higher-Stokes order Raman conversion to the near IR: high efficiency and brightness via a capillary waveguide amplifier

Efficient Raman conversion in H<sub>2</sub> gas from 0.53 µm to third Stokes (S<sub>3</sub>) at 1.58 µm has been demonstrated using an oscillator/amplifier configuration. Seed radiation from the oscillator controls the divergence of the Stokes beams and a capillary amplifier...

Description
Summary:Efficient Raman conversion in H<sub>2</sub> gas from 0.53 µm to third Stokes (S<sub>3</sub>) at 1.58 µm has been demonstrated using an oscillator/amplifier configuration. Seed radiation from the oscillator controls the divergence of the Stokes beams and a capillary amplifier configuration enhances the conversion. An overall 9% photon conversion efficiency to S<sub>3</sub> is achieved with the S<sub>3</sub> beam divergence twice the diffraction limit. Photon conversion efficiency within the amplifier is ~20%.
