    Abstract: A glaze encapsulated solid-state laser component (30). The novel laser component (30) includes a core (10) and a cladding (32) of ceramic glaze disposed on a surface of the core (10). In an illustrative embodiment, the core (10) 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 (32) can be applied by coating the core (10) 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 (10), and then fusing the pre-formed strips to the core (10) in a secondary firing cycle.

    Abstract: Methods and constructions for cryogenically cooled solid state lasers are provided that allow the cooling channels to be embedded within the heat sinks used to conductively cool the laser medium. Several gain medium geometries are disclosed that are compatible with efficient and straight forward cryogenic cooling techniques using practical pump chamber designs while eliminating the need for the pump light to traverse the cryogenic layers and allowing for smooth temperature cycling. A number of active material configurations that can be generally adapted for pumping by high power diodes - including slab, thin disk, active mirror and rod geometries - are shown to be compatible with the cryogenic cooling approaches of the invention. Modeling results based on the preferred cooling configurations indicate substantial improvement in the performance of common solid state lasers, including Nd and Yb-doped lasers.

    Abstract: An edge-pumped solid state thin slab laser apparatus is disclosed that is power scalable to well over 150 W for either multimode or near single transverse mode operation. A slab thickness is selected that is small enough to minimize thermal effects for a straight through beam yet large enough to allow efficient direct coupling of pump light from high power diode array stacks while also keeping the gain to within manageable levels for pulsed operation. Cooling of the slab is provided conductively, preferably by contact with metal blocks of high thermal conductivity. The edge-pumped solid state thin slab laser provides a near-one dimensional temperature gradient and heat flow direction that is perpendicular to the laser signal plane of propagation. The width of the slab is selected so as to maximize pump absorption length for a given laser material and both one and two-sided pumping schemes can be accommodated by the basic slab laser platform, depending on power, mode and beam quality requirements. The output power from the edge-pumped thin slab is generally scalable with slab length and the power available from diode array stacks used to pump the slab. The broad faces of the slab comprising the active medium may be coated with a material that is reflective at the pump wavelength or the slab can be sandwiched between two layers of dielectric of lower index of refraction so as to allow guiding of the pump light for better homogenization of the absorption, and hence the gain profile.
