摘要

A method of sealing an aperture formed in a discharge tube using a laser beam. A tube having the aperture to be hermetically sealed is placed in a vessel having a window which transmits a laser beam. The aperture is covered with a blockade member. The blockade member is irradiated with the laser beam in order to melt the blockade member and seal the aperture.
