ABSTRACT:
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.
