Dynamical Study on the Ultra-Short Pulsed Laser in the Water Medium and Skin Tissue and Comparing Obtained Results
Journal Title: International Journal of Fundamental Physical Sciences - Year 2014, Vol 4, Issue 1
Abstract
Interest on the ultra-short laser has increased continually over the past decade. Scientists have an excellent power medical resource and the use of this resource will assist in the development of sustainable medical procedures. Scientists with its many technologies and significant medical range-might are expected to have considerable potential for treating skin cancer. In this paper influences, the critical electron density and radiation intensity on the free-electron density for the ablation on the epidermis and dermis tissues are investigated. Our research work show existing of an inverse relationship between intensity radiations of laser pulsed and distance of focal spot with time-dependent of free-electron density. This case is proper for skin cancer treatment. Also, our calculations for each medium (water and skin tissue)show that optimum time-dependent free electron density for dermis layer at angle 16˚ and 22˚ which is a function of wavelength, beam width, beam radius, the amplitude of the beam radiation strength and pulse duration is more than for epidermis layer.
