A glaze soldered solid-state laser active medium. The novel laser active
medium includes a first section of a first material, a second section of
a second material, and a layer of ceramic glaze joining the two sections.
The first and second materials may be identical, similar, or dissimilar,
and may include crystals or ceramics. The glaze is a multi-oxide eutectic
ceramic glaze having a refractivity, light absorption, thermal expansion,
and fusion temperature that are compatible with the first material. The
sections are joined using a novel glaze soldering process that includes
the steps of positioning the sections, applying the ceramic glaze between
the sections, and firing the glaze to solder the sections together.
