 We developed a new system that utilizes nanosecond slash subnanosecond pulsed laser excitation in holocore photonic crystal fiber, HCPCF, based fiber enhanced Raman spectroscopy, FERS, to induce stimulated Raman scattering, SRS, enhancement for gas analysis. The results demonstrated the effectiveness of the system and an energy threshold for SRS initiation was experimentally observed. The SRS-capable FERS system shows great potential for analyzing complex gases such as propene, which is a volatile organic compound, VOC, gas, serving as a biomarker in human breath for lung cancer and other human diseases. This work contributes to the advancement of gas analysis and opens alternative avenues for exploring novel Raman enhancement techniques. This article was authored by Mariam Sher-Mohamed, Michael A.
