Improved beam control in surgical CO2 laser systems

摘要

Abstract: This paper deals with the improvement of the characteristics of the CO$-2$/ lasers used in surgical systems, particularly the design of single mode laser tubes with high output power density per unit length, the active control and monitoring of laser power level and its stability during long periods, the precise control of the irradiation time when the exposure regimes are diversified and the safety measures against uncontrolled irradiation, as well as the design of new beam delivery systems and specialized interfaces between the laser surgical units and the operating theatre. !7
