Abstract
A YAG ceramic bonded body in which a YAG ceramic and a YAG ceramic or optical glass are bonded, wherein the YAG ceramic bonded body comprises glass as a bonding layer, and has a rate of change of transmittance that is within 7%. An object of this invention is to provide a bonded body in which a YAG ceramic and a YAG ceramic are bonded, or a bonded body in which a YAG ceramic and optical glass are bonded, and which is capable of suppressing the reflection of light at the bonded interface, as well as the production method thereof.
Claims12
A YAG ceramic bonded body for use in a laser application, wherein a YAG ceramic as a laser medium and a YAG ceramic or optical glass as a light-absorbing layer are bonded, excitation light is introduced from the light-absorbing layer placed around the laser medium, and laser is output in a direction that is vertical to an incident direction of the excitation light from the laser medium, wherein the YAG ceramic bonded body comprises glass as a bonding layer for bonding the laser medium and the light-absorbing layer, and has a rate of change of transmittance that is within 7%, wherein the glass as a bonding layer is selected from the group consisting of alkalisilicate-based glass material, aluminosilicate-based glass, borosilicate-based glass, germanosilicate-based glass, and bismuth borate-based glass.
