ABSTRACT:
The object of the present invention is to prevent generation of leak caused by deterioration of a frit glass component at AlN/KB glass sealing section which is caused by discharge at the time of laser tube operation.
In the present invention, a high fusing point glass made up of a zinc/boric acids material is used at the sealing section of AlN/KB glass, adding to use a conventional low fusing point glass made up of a lead/sillic acids material. By means of this, it is possible to reduce the number of bubbles generation on the sealing interface of an AlN component and a low fusing point glass and to prevent deterioration of the low fusing point glass at laser tube operation and leak at the sealing section.
