随着激光在医学临床的广泛应用,功率小于50Ｗ的ＣＯ2激光器远远满足不了使用要求。有些临床要求激光经导光臂从导光头出射的功率达60Ｗ,特别是封离型ＣＯ2激光器,长期使用其工作气体还原再生能力弱,功率逐渐衰减。这就要求激光器自身输出功率达到100Ｗ,才能保证激光器在临床上 With the wide application of laser in clinical medicine, CO2 lasers with power less than 50W can not meet the requirements. Some clinical requirements of the laser light guide arm through the light guide from the power output of 60W, especially sealed-off CO2 laser, long-term use of its working gas reduction regeneration capacity is weak, the power gradually decay. This requires the laser output power of its own 100W, in order to ensure the laser in the clinic
