医学临床上正在开展应用激光治疗肿瘤的研究。将激光束直接作用于肿瘤组织,利用激光的光、热、压力、电磁场等效应,使肿瘤组织碳化或气化,在极短时间内达到去除病变的目的。碳化,所需激光器的功率较小,它将肿瘤组织表面烧成焦碳,但在焦碳层形成后,阻碍激光束进一步深入下层组 Medical clinical research is being carried out using laser treatment of tumors. The laser beam directly on the tumor tissue, the use of laser light, heat, pressure, electromagnetic fields and other effects, the tumor tissue carbonization or gasification, in a very short period of time to achieve the purpose of removing lesions. Carbonization, the laser power required is small, it burns the surface of the tumor tissue into coke, but after the coke layer is formed, the laser beam is prevented from further penetrating into the lower layer group
