A high power laser, such as CO2 or LD, is necessary for the sample heating in the container less processing. The high power laser is expensive generally, therefore that interrupt the spread of the container less processing of high temperature condition. Recently, a glass tube CO2 laser is provided, which is used as a heat source of computer controlled laser cutter. The glass tube CO2 laser is quite inexpensive, however we can hardly find the information of how to use it. Then, I actually bought the CO2 laser whose maximum output is 100 watt and try to set up it by myself with trial and error for testing the performance. I describe a way to the setup and the result of the first emission of this laser.
