High-resolution continuous-wave coherent anti-Stokes Raman spectroscopy in a supersonic jet.
We have obtained high-resolution cw coherent anti-Stokes Raman spectra of the nu(1) Q branch of methane in an underexpanded supersonic jet at temperatures as low as 31.5 K and pressures below 2 Torr.
متن کاملMicrofluidic device for continuous single cells analysis via Raman spectroscopy enhanced by integrated plasmonic nanodimers.
In this work a Raman flow cytometer is presented. It consists of a microfluidic device that takes advantages of the basic principles of Raman spectroscopy and flow cytometry. The microfluidic device integrates calibrated microfluidic channels- where the cells can flow one-by-one -, allowing single cell Raman analysis. The microfluidic channel integrates plasmonic nanodimers in a fluidic trappin...
متن کاملSingle-shot detection of bacterial endospores via coherent Raman spectroscopy.
Recent advances in coherent Raman spectroscopy hold exciting promise for many potential applications. For example, a technique, mitigating the nonresonant four-wave-mixing noise while maximizing the Raman-resonant signal, has been developed and applied to the problem of real-time detection of bacterial endospores. After a brief review of the technique essentials, we show how extensions of our e...
متن کاملCoherent Raman Spectroscopy in Gases
The instrumental resolution i n nonlinear coherent Raman spectroscopy is determined by the convoluted linewidths of the lasers used fo r excitation. This i s of special importance fo r the investigation of high resolution rotation-vibrational spectra of gases. It is now possible not only to determine l ine positions with accuracies better than cm-I, but also to study linewidths as a function of...
متن کاملCoherent broadband continuous-wave terahertz spectroscopy on solid-state samples
Measuring the complex dielectric function ε(ω)= ε1 + iε2 of solidstate samples in the terahertz frequency range with high spectral resolution remains difficult. Using a continuous-wave terahertz spectrometer based on photomixing in the frequency range from 60GHz to 1.8 THz, we obtain the most precise data of ε(ω) reported to date for the well-studied example of α-lactose monohydrate. We are abl...
