Continuous-Wave Coherent Raman Spectroscopy via Plasmonic Enhancement [PDF]

Scientific Reports, 2019
AbstractIn this paper, we report a successful combination of stimulated Raman spectroscopy (SRS) and surface-enhanced Raman scattering (SERS) using cw laser sources and gold/silica nanoparticles with embedded reporter molecules. We describe the preparation method for our gold/silica nanoparticles as well as the effect of probe wavelength, pump and ...

Real-time Continuous Wave Terahertz Spectroscopy with 2 THz Bandwidth

, 2022
S.738-739Until now, real-time acquisition of terahertz (THz) spectra has been an unique feature of time-domain spectroscopy (TDS) systems. However, fast acquisition of broadband THz signals can be a strength of continuous-wave (cw) THz as well, when a ...

Towards realisation of an efficient continuous wave terahertz source using quantum dot devices [PDF]

, 2019
A continuous wave (CW) terahertz source emitting in a broad frequency range (1-5THz) is promising towards achieving a compact, high power, finely tunable, room temperature terahertz generation system which will be of immense significance towards the ...

Cantilever-Enhanced Photoacoustic Spectroscopy of Radioactive Methane [PDF]

, 2020
We report the first high-resolution spectroscopy study of radiocarbon methane, 14CH4. Several absorption lines of the fundamental vibrational band n3 were measured using a continuous-wave mid-infrared optical parametric oscillator with cantilever ...

Pulsed and continuous-wave magnetic resonance spectroscopy using a low-cost software-defined radio

AIP Advances, 2019
Software-defined radios (SDRs) constitute a modern and highly adaptive realization of a radio-frequency transceiver system. This work demonstrates how a particular radio transceiver, namely, the LimeSDR board, can be configured for pulsed and continuous ...

Optomechanical Cooling in a Continuous System

Physical Review X, 2018
Radiation-pressure-induced optomechanical coupling permits exquisite control of micro- and mesoscopic mechanical oscillators. This ability to manipulate and even damp mechanical motion with light—a process known as dynamical backaction cooling—has become
