Abstract

LASER is defined as an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. It can propagate in a straight line and occur in a wide range of wavelength, energy/power and beam-modes/configurations. They find wide applications in academic, commercial and scientific domains ranging from very simple to complex applications. This research provides an overview of the application of lasers for thermal protection from the laser irradiation for protective clothing. In this work, aerogel particles in granular form were embedded between glass and kevlar fabric and the impact of laser irradiation on the samples was studied. 150 Flexi Marcatex laser instrument was used for this experiment with the new experimental set-up. Samples with different mass of aerogel was sandwiched between the glass and kevlar fabric and its resistance to thermal radiation from laser rays was studied. The surface temperature of kevlar fabric was recorded from the backside and it was observed from the results that the surface temperature of kevlar fabric decreased with the increase in mass of aerogel. All data was statistically analysed in Matlab and Linear fit model was plotted with residuals to see the difference from observed and fitted datas.
