二氧化碳激光已经成为最灵活、最有用的治疗工具之一,它应用在耳鼻喉科范围内,特别是在喉病的治疗上,愈来愈普遍,它给外科医生提供了一种从未有过的能精确地被控制的能源。激光的英文名LASER,是Light Amplification by Stimulated Emission of Radiation每一字第一字母的拼写,直译就是“受激发射光”。激光是一束相干光,一束单色的平行光,波长几乎完全一致,它不象从一般光源发出的光线按照负二次方定律向四周扩散。激光发出后,所到之处光束直径实际不增大,如同一根光柱。当它和物体接触并被物体吸收后,大能量的光转化为强烈的热 Carbon dioxide laser has become one of the most flexible and useful treatment tools. Its application in the ENT range, especially in the treatment of laryngeal diseases, is more and more common. It gives the surgeon a chance to have never had Can precisely control the energy. Laser English name LASER, Light Amplification by Stimulated Emission of Radiation each word spelling, literal translation is “stimulated emission.” Laser is a bundle of coherent light, a bundle of monochromatic parallel light, the wavelength is almost exactly the same, it does not like the light from the general light source in accordance with the law of negative quadratic diffusion to the surrounding. After the laser is emitted, the diameter of the beam where it is actually does not increase, as a beam. When it comes into contact with the object and is absorbed by the object, the energy of the light transforms into intense heat
