Since its discovery, the laser has been intensively investigated and used in medicine, first in ophthalmology then in ear, nose and throat surgery, gynaecology, neurosurgery etc. Development spans from the ruby and argon lasers in outpatient eye surgery to the carbon dioxide and Nd:YAG lasers in the operating theatres and further on to the PDT-dye lasers, excimer and solid state angioplasty lasers or flash lamp pumped "gallstone cracker" lasers. The CO2-Nd: YAG laser combination will be described as the state-of-art surgical laser. This simultaneous, coaxial and coherent combination laser offers a new possibility to cut and coagulate effectively at the same time. Operating times are shortened and bleeding volumes minimised. The CO2-Nd: YAG laser represents a new type of interaction between laser and tissue, laser enhanced tissue absorption, which will be described.
自激光被发现以来，人们对其进行了深入研究并应用于医学领域，最初用于眼科，随后应用于耳鼻喉科手术、妇科、神经外科等。其发展历程涵盖从门诊眼科手术中使用的红宝石激光和氩激光，到手术室中使用的二氧化碳激光和钕钇铝石榴石激光，再到光动力疗法染料激光、准分子激光和固态血管成形激光，或闪光灯泵浦的“胆结石破碎”激光。二氧化碳 - 钕钇铝石榴石组合激光将被描述为最先进的手术激光。这种同时、同轴且相干的组合激光提供了一种同时有效切割和凝固的新可能性。手术时间缩短，出血量最小化。二氧化碳 - 钕钇铝石榴石激光代表了激光与组织之间一种新型的相互作用，即激光增强组织吸收，将对此进行描述。
