Mid-Infrared supercontinuum absorption spectroscopy beyond 7 µm based on free Arsenic chalcogenide fiber [PDF]

open access: yesEPJ Web of Conferences, 2023
Mid-Infrared methane (CH4) spectroscopy results were obtained in band III beyond 7 µm. To achieve this, the generation of supercontinuum covering the spectral range between 5 and 12 µm was realized by using purified chalcogenide optical fibers free of ...

Efficient Optically-Pumped Semiconductor Optical Amplifier in a Coupled-Waveguide Configuration: A Novel Proposal

open access: yesIEEE Photonics Journal, 2021
We propose an efficient scheme of optical pumping and a compact design of an optically-pumped semiconductor optical amplifier (OP-SOA), with gain characteristics which are qualitatively similar to that of conventional (electrically-pumped) SOA.

Polarizing ³He by Spin Exchange with Potassium [PDF]

open access: yes, 2004
We present experimental studies on the spin-exchange optical pumping of ³He using alkali metal potassium vapor. High ³He polarizations are achieved using lower laser power than traditional rubidium-³He pumping studies.

Optical Pumping and Vibrational Cooling of Molecules [PDF]

open access: yesScience, 2008
The methods producing cold molecules from cold atoms tend to leave molecular ensembles with substantial residual internal energy. For instance, cesium molecules initially formed via photoassociation of cold cesium atoms are in several vibrational levels ν of the electronic ground state.
