Abstract

We have developed a device whereby a laser beam is converted to a square and uniform output intensity distribution. This device consists of a square pillar. The laser beam enters the square pillar at a specified incident angle, and uniform output intensity distribution is obtained at the end of the pillar. We describe the theory and the characteristics and uses of this device. Furthermore, we developed the ruby and argon laser systems in which this device is incorporated as the handpiece. It is mainly for clinical use, but also for industrial purposes such as soldering and marking.
