Abstract

A high power He-Ne laser, including two laser tubes having rectangular discharge cross-section and giving about 350 mw total output power, has been designed and elaborated. The laser beams can be coupled into a quartz optic fiber by optical system. This laser has been applied to photodynamic therapy (PDT) for cancer. Its complete response rate is about 60% in 44 clinical cases. In this paper, the design principle and the experimental results of this high power He-Ne laser and its patient response of PDT for cancer are introduced. In addition, the curalive effects of PDT using different lasers are also discussed.
