Quartz tuning forks resonance frequency matching for laser spectroscopy sensing. [PDF]

open access: yesPhotoacoustics, 2022
In this paper, we report on the performance of quartz tuning fork (QTF) based laser spectroscopy sensing employing multiple QTFs. To avoid that resonance frequency mismatching of the QTFs degrades the sensor performance, two types of resonance frequency ...

Laser spectroscopy for the study of exotic nuclei [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2022
Investigation into the properties and structure of unstable nuclei far from stability remains a key avenue of research in modern nuclear physics. These efforts are motivated by the continual observation of unexpected structure phenomena in nuclei with ...

Coherent laser spectroscopy of highly charged ions using quantum logic [PDF]

open access: yesNature, 2020
Precision spectroscopy of atomic systems1 is an invaluable tool for the study of fundamental interactions and symmetries2. Recently, highly charged ions have been proposed to enable sensitive tests of physics beyond the standard model2–5 and the ...

Proton-electron mass ratio from laser spectroscopy of HD+ at the part-per-trillion level [PDF]

open access: yesScience, 2020
A very precise ratio The value of the ratio of the masses of the proton and the electron has a bearing on the values of other physical constants. This ratio is known to a very high precision. Patra et al. improved this precision even further by measuring

Laser spectroscopy for breath analysis: towards clinical implementation. [PDF]

open access: yesAppl Phys B, 2018
Detection and analysis of volatile compounds in exhaled breath represents an attractive tool for monitoring the metabolic status of a patient and disease diagnosis, since it is non-invasive and fast. Numerous studies have already demonstrated the benefit

Recent progress in laser spectroscopy of the actinides [PDF]

open access: yes, 2020
The interest to perform laser spectroscopy in the heaviest elements arises from the strong impact of relativistic effects, electron correlations and quantum electrodynamics on their atomic structure.

Structural trends in atomic nuclei from laser spectroscopy of tin

open access: yesCommunications Physics, 2020
Tin is the chemical element with the largest number of stable isotopes. Its complete proton shell, comparable with the closed electron shells in the chemically inert noble gases, is not a mere precursor to extended stability; since the protons carry the ...

Raman Spectroscopy Investigation of Graphene Oxide Reduction by Laser Scribing

open access: yesC++ Conference, 2021
Laser scribing has been proposed as a fast and easy tool to reduce graphene oxide (GO) for a wide range of applications. Here, we investigate laser reduction of GO under a range of processing and material parameters, such as laser scan speed, number of ...

Double face of cytochrome c in cancers by Raman imaging

open access: yesScientific Reports, 2022
Cytochrome c (Cyt c) is a key protein that is needed to maintain life (respiration) and cell death (apoptosis). The dual-function of Cyt c comes from its capability to act as mitochondrial redox carrier that transfers electrons between the membrane ...
