Abstract
Abstract The laser carbon dioxide CO2 is one of the most important in medicine, particularly in the overlap for surgical owned because of the unique characteristics of higher long wavelength 10.6 m (that is, it has a high thermal energy, as well as that of the high water absorption viability of this wavelength).In this study CO2 laser was used to study the threshold limit, depth of penetration and thermal effects, as well as the absorption coefficient calculation. Laser pulse (Pw Mode) carbon dioxide of power (5-20) watt of different frequencies (10, 20, 30, 40, 50) Hz was used to study the depth of penetration laser beam to the tissue. Penetration depth measured note that at increase the power increase the depth of penetration for all frequenciesas well as the depth of penetration is increasing at the same power by increasing the frequency. There is no difference in the thermal effects lasers at power (1, 1.5) watt at frequency (5, 10, 20, 30) Hz. While at power more than 1.5 wattclearly shows the impact of lasers at the tissue.We find that the impact of laser beam in the tissue is burned in the textile as itseems Note edge of tissue, which appear blackening which represents the carbon from the combustion backward as well as changing the color of the fabric.
