The output power of high power He-Ne laser with flat discharge tube can be doubled in comparison to the traditional one with same discharge length. For example, the output power of this He-Ne laser of 1.4 meter long can be above 130 mW. This paper introduces and discusses briefly some key technical problems of this laser, including manufacture of flat glass tube and design of the adjustable structure of laser tube.
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.
