Abstract

PURPOSE: To prvent breakage, crack, hole of light transmitting insulation tube from heat impact by covering it in an enclosing fashion with laser beam absorbing and heating vover so that at least part of it contacts the enclosed body.
CONSTITUTION: Continuous beam (for example, wave length 10.6Μm, output 250W ) is radiated from carbonic acid gas laser equipment 7 and, through germanium window which transmits almost 100% of infrared rays of wave length 10.6Μm, is irradiated to absorbing and heating cover 3 made of tantalum. At the same time, rotator 4 gives a rotation to niobium cap 6, glass solder 5, light transmitting alumina ceramic tube 2 and the laser beam absorbing and heating cover made of tantalum, and this absorbing and heating cover will be heated to about 1,560°C in about one minute and a half after the laser beam of about 10mm in diamefter is irradiated. This heat is used for making the tube
