一、绪言医用激光器是指以激光刀为核心的凝固装置。它需要一种导光系统把激光从振荡器引至病人待治部位。这种系统是提高机器性能的重要因素。在光通信方面,激光器的导光系统采用光学纤维。这一技术业已成熟,并进入了实用阶段。但是,它能传输的波段有限,只能用于半导体激光器。供大功率激光器传输用的光学纤维尚未研制成功。 First, the introduction Medical laser refers to the laser knife as the core of the coagulation device. It requires a light guide system to direct the laser from the oscillator to the site to be treated by the patient. This system is an important factor in improving machine performance. In optical communications, the laser light guide system uses optical fibers. This technology has matured and entered a practical stage. However, it can transmit the band is limited, only for semiconductor lasers. Optical fibers for transmission of high-power lasers have not been successfully developed.
