Medical application of laser pulse (Pw Mode) and continuous (cw Mode) carbon dioxide

Abstract

AbstractThe laser carbon dioxide CO2 is one of the most important in medicine, particularly in theoverlap for surgical owned because of the unique characteristics of higher longwavelength 10.6 m (that is, it has a high thermal energy, as well as that of the highwater absorption viability of this wavelength).In this study CO2 laser was used to studythe threshold limit, depth of penetration and thermal effects, as well as the absorptioncoefficient calculation. Laser pulse (Pw Mode) carbon dioxide of power (5-20) watt ofdifferent frequencies (10, 20, 30, 40, 50) Hz was used to study the depth of penetrationlaser beam to the tissue. Penetration depth measured note that at increase the powerincrease the depth of penetration for all frequenciesas well as the depth of penetration isincreasing at the same power by increasing the frequency. There is no difference in thethermal effects lasers at power (1, 1.5) watt at frequency (5, 10, 20, 30) Hz. While atpower more than 1.5 wattclearly shows the impact of lasers at the tissue.We find that theimpact 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 aswell as changing the color of the fabric.
