Abstract
A glaze encapsulated solid-state laser component. The novel laser component includes a core and a cladding of ceramic glaze disposed on a surface of the core. In an illustrative embodiment, the core is fabricated from a laser gain medium and the cladding material is a multi-oxide eutectic ceramic glaze having a refractivity slighter lower than the refractivity of the gain medium, such that the glaze layer forms a step-index refractivity interface cladding that can effectively suppress parasitic oscillations in the core gain medium. The glaze cladding can be applied by coating the core with the glaze and then firing the glaze coated core, or by fabricating pre-formed cladding strips from the ceramic glaze in a first firing cycle, mounting the pre-formed strips to the core, and then fusing the pre-formed strips to the core in a secondary firing cycle.
