Heat Generation in Laser Irradiated Tissue
Journal of Biomechanical Engineering, 1989Many medical applications involving lasers rely upon the generation of heat within the tissue for the desired therapeutic effect. Determination of the absorbed light energy in tissue is difficult in many cases. Although UV wavelengths of the excimer laser and 10.6 μm wavelength of the CO2 laser are absorbed within the first 20 μm of soft tissue ...

Laser Heated Ferromagnetic Simulations
2014In this work, we show a model of ferromagnetic material heated by a laser pulse. The laser creates a pattern of circles on the ferromagnetic materials with hot regions heated up to 3,000 K and cold regions at 100 and 400 K. In our model the Landau-Lifshitz-Gilbert equation for a macrospin and spin temperature is passed through stochastic field. We show

We are concerned with heating metals and semiconductors to produce a change in their properties in the heated region only. The change may be a solid to solid conversion as in heat treating steels, a solid to liquid to solid conversion as in semiconductor annealing or a solid-to-liquid-to vapor conversion as in cutting or drilling.

Heat treatments serve a wide range of purposes in today’s material technology. Examples include softening or hardening of metals, “annealing” of crystals, dopant diffusion in semiconductors, compound formation in mixtures or thin-film couples, oxide layer growth, polymerization of plastics and many others.

The irradiation of tissue by laser light results in the absorption of energy. Since this is a fully dissipative process, the consequence is that the increment in energy is expressed entirely as a heat transfer absorbed by the tissue. In conjunction with this absorption, there will be an increase in the energy stored locally in the tissue as a function ...

Laser heating of an optical fiber
Applied Optics, 1976For use in absorption measurements in low-attenuation glass fibers, we calculate the periodic temperature rise at the surface of a glass cylinder heated by a chopped laser beam. Specifically, we give the mean temperature, setting the operating temperature of the experiment, and the peak-to-peak temperature, determining the sensitivity of the ...

Soot diagnostics based on laser heating
Applied Optics, 1984Through numerical calculations we have investigated the possibility of developing soot diagnostics based on laser heating of the soot particles. Two strategies, one using the laser-modulated incandescence of the particles, and the other using direct detection of the evaporated C2 molecules, were examined. Both strategies can yield size distribution and
