The erbium-doped yttrium aluminium garnet (Er:YAG) laser has emerged as a possible alternative to conventional methods of bone ablation because of its wavelength of2.94 μm, which coincides with the absorption peak of water. Over the last decades in several experimental and clinical studies, the widespread initial assumption that light amplification for stimulated emission of radiation […]
I fondamenti del laser
/ studio
The word “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers are finding ever increasing military applications — principally for target acquisition, fire control, and training. These lasers are termed rangefinders, target designators, and direct-fire simulators. Lasers are also being used in communications, laser radars (LIDAR), landing systems, laser pointers, guidance […]

Storia del laser in dermatologia
/ studio
In the 1950s, based on the theory of stimulating radiant energy published by Albert Einstein in 1916, the collaboration of physicists and electrical engineers, searching for monochromatic radiation to study the spectra of molecules, led to the invention of the first laser in 1960. Ophthalmologists and dermatologists were the first to study the biological effects […]
Applicazioni LLLT sui tessuti molli
/ studio
Gli effetti della biostimolazione laser a bassa intensità (Low Level Laser Therapy, ovvero LLLT) sono, come abbiamo potuto vedere nella precedente cartella, un effetto antiflogistico, un effetto antibatterico, un effetto biostimolativo ed un effetto antalgico. Autore Gian Franco Franchi
LLLT applications on soft tissues
/ studio
The effects of low intensity laser biostimulation (Low Level Laser Therapy or LLLT) are, as we saw in the previous folder, an anti-inflammatory effect, an antibacterial effect, an effect bio stimulators and analgesic effect.

MODELLING AND MEASUREMENTS OF LASER-SKIN THERMAL INTERACTION
/ studio
Thermal laser-skin interaction has principal role in laser dermatology, and it can be successfully modelled and measured. For modelling, the seminar covers all the steps involved, which range from determination of laser beam and skin optical properties, treatment of light propagation in the tissue, thermal diffusion of heat to thermal effects prediction. As a simple […]
LASER RADIATION PROPAGATION AND HEAT TRANSFER INTO CELLS AND TISSUES
/ studio
In this paper we shall approach only the interaction of laser radiations with highly scattering and/or absorbing biological materials (i.e., opaque materials). The photon multiple scattering by cells and tissues is approached from the perspective of the general propagation theory (i.e., simple diffusion) of a particular physical magnitude, provoked by its conjugated gradient. In this […]
