Abstract
We study on the new advances in laser cell surgery for skin cancer treatment and investigate on the working mechanisms of femtosecondlaser. Also, influences of the critical electron density and radiation intensity on the free-electron density for ablation on the epidermis and dermis tissues are investigated. Our studies on this work, show that if the amount of radiation intensity of pulsed laser is increased then the distance of focal spot is decreased also the amount of time dependent free- electron density become more and more, such that this case is proper for skin cancer treatment. Also, our calculations for 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, amplitude of the beam radiation strength and pulse duration is more than for epidermis layer
