Higher-Stokes order Raman conversion to the near IR: high efficiency and brightness via a capillary waveguide amplifier
Higher-Stokes order Raman conversion to the near IR: high efficiency and brightness via a capillary waveguide amplifier
Efficient Raman conversion in H2 gas from 0.53 µm to third Stokes (S3) 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 S3 is achieved with the S3 beam divergence twice the diffraction limit. Photon conversion efficiency within the amplifier is ~20%.

Abstract
Efficient Raman conversion in H2 gas from 0.53 µm to third Stokes (S3) 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 S3 is achieved with the S3 beam divergence twice the diffraction limit. Photon conversion efficiency within the amplifier is ~20%.
