Improved sensitivity gas detection by spontaneous Raman scattering [PDF]

open access: yesApplied Optics, 2009
Accurate, real-time measurement of the dilute constituents of a gaseous mixture poses a significant challenge usually relegated to mass spectrometry. Here, spontaneous Raman backscattering is used to detect low pressure molecular gases. Rapid detection of gases in the approximately 100 parts in 10(6) (ppm) range is described.

Chirped pulse Raman amplification in plasma [PDF]

open access: yes, 2011
Raman amplification in plasma has been proposed to be a promising method of amplifying short radiation pulses. Here, we investigate chirped pulse Raman amplification (CPRA) where the pump pulse is chirped and leads to spatiotemporal distributed gain ...

Intrapulse Correlated Dynamics of Self-Phase Modulation and Spontaneous Raman Scattering in Synthetic Diamond Excited and Probed by Positively Chirped Ultrashort Laser Pulses

open access: yesPhotonics, 2023
In synthetic diamond plates, the intrapulse-correlated dynamics of self-phase modulation and spontaneous nonresonant Raman scattering by center-zone optical phonons were for the first time directly investigated for tightly focused (focusing numerical ...

Revisiting spontaneous Raman scattering for direct oxygen atom quantification [PDF]

open access: yesOptics Letters, 2021
In this Letter, the counterintuitive and largely unknown Raman activity of oxygen atoms is evaluated for its capacity to determine absolute densities in gases with significant O-density. The study involves C O 2 microwave plasma to generate a self-calibrating mixture and establish accurate cross sections for
