Raman wavelength conversion in a multipass cell
نویسندگان
چکیده
Positively chirped femtosecond pulses at 1030 nm are wavelength-converted using spontaneous and stimulated Raman scattering in a potassium gadolinium tungstate crystal inserted inside multipass cell. Recirculation the cell material allows both high conversion efficiency good spatial beam quality for generated Stokes beams. The converted can be compressed to sub-picosecond duration. Multipass cells could an appealing alternative other shifter implementations terms of thermal effects, control cascade, overall output quality.

Raman induced wavelength conversion in scaled Silicon waveguides
Parametric Raman nonlinearities in Silicon waveguides is used to demonstrate wavelength conversion from Stokes to anti-Stokes channels. The effects of two photon absorption and free carrier nonlinear losses on the conversion process have also been analyzed. We find that scaling down the waveguide dimensions to submicron sizes is advantageous in terms of increasing the Raman nonlinearities and r...
متن کاملWavelength conversion in silicon using Raman induced four-wave mixing
Silicon integrated optics has emerged as an attractive technology for realizing passive devices because of the efficient silicon-on-insulator sSOId guiding structures and foundry compatible processing technology. However, silicon is generally perceived to be devoid of active optical properties that are needed to realize more sophisticated optical functions such as, amplification and wavelength ...
متن کاملWavelength conversion using parametric Raman scattering in Silicon microstructures
We demonstrated conversion of optical signals from 1550nm band to the 1300nm band in silicon waveguides. The conversion is based on parametric Stokes to anti-Stokes coupling using the Raman susceptibility of silicon. Achieving high conversion efficiency requires phase matching in the waveguides as well as means to reduce waveguide losses including the free carrier loss due to two photon absorpt...
متن کاملWavelength Conversion in Silicon
This paper reviews recent results on wavelength conversion in Silicon. The conversion in the 1300 to 1550 range is achieved through parametric Raman coupling between the pump, Stokes and anti-Stokes waves. High signal-to-noise ratio is measured despite a limited conversion efficiency. Achieving high conversion efficiency requires phase matching in the waveguides as well as means to reduce waveg...
متن کاملWavelength Selectable Solid-State Raman lasers in the Visible and Ultraviolet Ranges
Solid-state Raman lasers are known as important sources at normally difficult to access wavelengths, and our recent studies have shown that they also form the basis of a class of wavelength selectable lasers. This paper summarizes our recent studies in wavelength selectable Raman lasers in the visible (532-650 nm) and ultraviolet (266-321 nm).
