Abstract The term laser is an acronym for ”Light Amplifica- tion by Stimulated Emission of Radiation”. in generals, a laser beam is generated when an out-foide power source vigorously dissipates energy into.the, laser medium, this energy will force the atoms in this medium into an excited state, released by a process called ’’Stimulated Emission’’ in the form of a light beam Laser beam)This beam is enormously intense, monochromatic and coherent. These properties of a controllable light beam of ouch high intensity are the basis for consideration of its use in micronurgerye Laser beam can be easily focused to cover areas, as small as 50 u at power densities of 10*000 watts/ am or moreo Numerous substances have been employed as laser souroeSO The most common used materials in medical lasers are the 002,and argon gases Differpnt, anesthetic t,eobni,ques are employed in the laser surgery, but what seems most important is that. |
