Journal ArticleDOI
Picosecond Laser Ablation of Dentine in Endodontics
TL;DR: It seems that cleaning and shaping of the root canal walls during endodontic therapy with the picosecond Nd:YAG laser application may be possible in the future.
Journal ArticleDOI
A detailed analysis of the MIG spectrum for the development of laser-based seam tracking sensors
TL;DR: In this paper, a detailed series of measurements of the spectrum of the light emitted from a MIG welding arc is presented, and the results are of great importance for the design of any optical or vision system working close to a welding arc.
Journal ArticleDOI
Generation of UV and VIS laser light by stimulated Raman scattering in H2, D2, and H2/He using a pulsed Nd:YAG laser at 355 nm
TL;DR: In this paper, photon conversion efficiencies of 50% and 27% were achieved at the first Stokes lines (S1) in H2 and D2, respectively, with energies ranging from a few mJ up to several tens of mJ.
Journal ArticleDOI
Laser induced autofluorescence studies of animal skin used in modeling of human cutaneous tissue spectroscopic measurements
E. Drakaki,Ekaterina Borisova,Mersini I. Makropoulou,Latchezar Avramov,Alexandros A. Serafetinides,Ivan Angelov +5 more
TL;DR: Laser‐induced autofluorescence spectroscopy is used for medical diagnostics of different tissue pathologies including cancer and it is very important to find the most appropriate, and close to the human skin, animal samples from the fluorescence point of view, which will allow the extrapolation of the animal data to human spectroscopic diagnostics.
Journal ArticleDOI
Four-wave mixing and parametric four-wave mixing near the 4P–4S transition of the potassium atom
M. Katharakis,M. Katharakis,N. Merlemis,Alexandros A. Serafetinides,Alexandros A. Serafetinides,T. Efthimiopoulos +5 more
TL;DR: In this article, two emission lines, one close to and one below the potassium 4P3/2 level, are reported for low pumping intensity, due to a parametric four-wave mixing process.
