Abstract
A face pumped slab laser includes a housing within a resonator cavity for housing a slab of host material and a light source for pumping the slab. The slab is mounted in a holder which is readily inserted in or retracted from the housing. The holder rigidly supports the slab without inducing stresses therein. The holder includes first and second longitudinal support members with generally U-shaped cross sections for engaging the top and bottom surfaces of the slab. Each end of the slab is engaged by two cooperating support members which have surfaces for receiving the periphery of the face of the slab. Ears on the first and second support members mate with brackets on support members at either end of the slab.
Claims7
A slab and holder for use in a face pumped slab laser comprising
- a body of solid state laser host material having a rectangular cross section with top and bottom surfaces, opposing side surfaces, and opposing end faces,
- first and second support members running the length of said body and positioned about the top and bottom surfaces of said body, respectively, each of said first and second support members including ears at each end,
- third and fourth generally planar support members each engaging a side surface of said body near ends of said body,
- said third and fourth members engaging opposite side surfaces and at opposite ends of said body;
- fifth and sixth support members configured to receive opposing ends of said body in engagement with a side surface, said top surface, and said bottom surface, each of said fifth and sixth support members engaging different side surfaces, each of said fifth and sixth members including a recessed portion for receiving one of said third and fourth members, and each of said fifth and sixth members including opposing bracket portions for receiving ears of said first and second support members.
For use in a face pumped slab laser, means for amplifying a light wave comprising:
- a housing having openings at opposing ends and means for passing a coolant fluid through said housing,
- excitation means mounted in said housing for providing excitation to atoms of a host material,
- a slab and holder removably mounted in said housing through said openings, said slab and holder including
- a body of solid state laser host material having a rectangular cross section with top and bottom surfaces, opposing side surfaces, and opposing end faces,
- first and second support members running the length of said body and positioned about the top and bottom surfaces of said body, respectively, each of said first and second support members including ears at each end,
- third and fourth generally planar support members each engaging a side surface of said body near ends of said body,
- said third and fourth members engaging opposite side surfaces and at opposite ends of said body, and
- fifth and sixth support members configured to receive opposing ends of said body in engagement with a side surface, said top surface and said bottom surface, each of said fifth and sixth support members engaging different side surfaces, each of said fifth and sixth members including a recessed portion for receiving one of said third and fourth members, and each of said fifth and sixth members including opposing bracket portions for receiving ears of said first and second support members.
