Efficient continuous-wave noise spectroscopy beyond weak coupling [PDF]
The optimization of quantum control for physical qubits relies on accurate noise characterization. Probing the spectral density $S(ω)$ of semi-classical phase noise using a spin interacting with a continuous-wave (CW) resonant excitation field has recently gained attention.

Continuous-wave cavity ringdown spectroscopy based on the control of cavity reflection
A new type of continuous-wave cavity ringdown spectrometer based on the control of cavity reflection for trace gas detection was designed and evaluated. The technique separated the acquisitions of the ringdown event and the trigger signal to optical switch by detecting the cavity reflection and transmission, respectively.

Quantum-Enhanced continuous-wave stimulated Raman spectroscopy
Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity, resolution and speed. However, sensitivity and speed of state-of-the-art stimulated Raman spectroscopy are currently limited by the shot-noise of the light beam probing the Raman process.

Controlling the optical pathlength in continuous-wave reflectance spectroscopy using polarization
We investigate potential improvements of continuous-wave diffuse reflectance spectroscopy within highly scattering media by employing polarization gating. Simulations are used to show the extent at which the effective optical pathlength varies in a typical scattering medium as a function of the optical wavelength, the total level of absorption, and the
