Abstract
A system for improving the thermal uniformity, beam quality and lasing efficiency of composite solid state lasers by reducing parasitic oscillations and confining the laserable medium to a location in the composite laser component where it is most efficient is provided. The improvements are accomplished by bonding one or more laser-inactive or laser-radiation-absorbing layers to a laserable medium.

A solid state laser device, comprising:
- an ionic lasing medium with a surface substantially parallel to an intended direction of propagation of generated laser radiation;
- and
- a non-lasing ionic medium optically contacted to said surface to form an essentially defect free interface, wherein said interface is permanently bonded using an adhesive-free diffusion bonding technique, wherein said non-lasing ionic medium is sapphire with a (0001) crystallographic plane aligned parallel to said surface.
A solid state laser device, comprising:
- an ionic lasing medium with a surface substantially parallel to an intended direction of propagation of generated laser radiation;
- and
- a non-lasing ionic medium optically contacted to said surface to form an essentially defect free interface, wherein said interface is permanently bonded using an adhesive-free diffusion bonding technique, wherein said ionic lasing medium has a refractive index which is higher than that of said non-lasing medium.
A solid state laser device, comprising:
- a core of an ionic lasing medium with a polygonal cross-section substantially perpendicular to an intended direction of propagation of generated laser radiation, said core having a plurality of surfaces substantially parallel to said intended propagation direction;
- and
- a cladding of laser-inactive material optically contacted to said plurality of surfaces to form a plurality of essentially defect free interfaces, wherein said plurality of interfaces are permanently bonded using an adhesive-free diffusion bonding technique.
A solid state laser array, comprising an alternating sequence of at least two ionic lasing layers and at least two laser-inactive layers optically contacted along adjacent surfaces to form a plurality of essentially defect free interfaces, wherein said plurality of interfaces are permanently bonded using an adhesive-free diffusion bonding technique, said plurality of interfaces substantially parallel to an intended direction of propagation of generated laser radiation.
A solid state electro-optic device with an ionic single crystalline material optically contacted to a sapphire substrate to form an essentially defect free interface, wherein said interface is permanently bonded using an adhesive-free diffusion bonding technique, wherein said sapphire has a (0001) crystallographic plane aligned parallel to said interface.
