Precisely applied heat from the touch of a laser not only can hide blemishes, but can also save lives. For many, laser surgery brings to mind highly refined incisions made by coherent light pulses. Cutting, however, is not the only action a laser can perform: Sometimes, all you need is a little heat. Aiming a properly chosen laser onto a blood vessel or other tissue section adds enough thermal energy that the tissue’s properties alter. When heat is applied to a blood vessel, the vein or artery deforms, or even withers away if enough energy is used. The ability of a laser...Read full article

    laser surgery
    Laser surgery refers to a medical procedure in which a laser, or focused beam of light, is used as a precision tool to cut, vaporize, coagulate, or otherwise modify tissues for therapeutic or surgical purposes. Lasers offer several advantages in surgery, including precision, minimal invasiveness, and the ability to target specific tissues without causing extensive damage to surrounding areas. The process of laser surgery involves the following key components: Generation of laser light:...
    photothermal effect
    The cause of some forms of laser injury in which tissue absorbs incident laser light and experiences a damaging rise in temperature. The severity of the damage is dependent on the rate of energy absorption, not on the total energy absorbed.
