Engineering nanoparticle features to tune Rayleigh scattering in nanoparticles-doped optical fibers

open access: yesScientific Reports, 2021
Rayleigh scattering enhanced nanoparticles-doped optical fibers are highly promising for distributed sensing applications, however, the high optical losses induced by that scattering enhancement restrict considerably their sensing distance to few meters.

Overview of lasers [PDF]

open access: yesIndian Journal of Plastic Surgery, 2008
Laser surgery of skin conditions having cosmetic implications has revealed the profound psychological benefits which are unmatched by any other modality of treatment either with or without a knife. An increasingly sophisticated understanding of the biophysics of laser-tissue interactions has lead to a more efficient utilization of the present ...

Magnetized fast isochoric laser heating for efficient creation of ultra-high-energy-density states

open access: yesNature Communications, 2018
It is desirable to deposit more energy in the dense plasma core to trigger the fusion ignition. Here the authors demonstrate enhanced energy coupling from laser to plasma core by using solid targets and guiding the transport of relativistic electron beam

Enhanced laser-driven proton acceleration via improved fast electron heating in a controlled pre-plasma

open access: yesScientific Reports, 2021
The interaction of ultraintense laser pulses with solids is largely affected by the plasma gradient at the vacuum–solid interface, which modifies the absorption and ultimately, controls the energy distribution function of heated electrons.

Promoting Immortalized Adipose-Derived Stem Cell Transdifferentiation and Proliferation into Neuronal-Like Cells through Consecutive 525 nm and 825 nm Photobiomodulation

open access: yesStem Cells International, 2022
Neuronal cells can be generated from adipose-derived stem cells (ADSCs) through biological or chemical inducers. Research has shown that this process may be optimized by the introduction of laser irradiation in the form of photobiomodulation (PBM) to ...
