Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
64 words
A cavity configuration for a solid-state laser as defined in claim 1 in which the saturable absorber is positioned adjacent to one of the mirrors, the aperture is positioned adjacent to the saturable absorber, an etalon is positioned adjacent to the aperture, the solid-state laser rod is positioned adjacent to the etalon and the other mirror is positioned adjacent to the solid-state laser rod.
Claim 2
Dependent Claim
68 words
A cavity configuration for a solid-state laser as defined in claim 1 in which the first mirror is convex and the second mirror is concave and both mirrors have a radius of curvature in the range of 1 to 20 meters and are arranged in the cavity so that the center of curvature of the concave mirror is proximate to the center of curvature of the convex mirror.
Claim 3
Dependent Claim
51 words
A cavity configuration for a solid-satate laser as defined in claim 3 in which the center of curvature of the concave mirror is between the center of curvature of the convex mirror and the convex mirror itself whereby the center of curvature of both mirrors is close to a concentric configuration.
Claim 4
Dependent Claim
49 words
A cavity configuration for a solid-state laser as defined in claim 1 in which the diameter of the aperture is approximately equal to the diameter of the fundamental transverse mode of the light beam emitted by the solid-state laser from the cavity measured at the exit to the cavity.
Claim 5
Dependent Claim
49 words
A cavity configuration for a solid-state laser as defined in claim 1 in which the diameter of the aperture is approximately equal to the diameter of the fundamental transverse mode of the light beam emitted by the solid-state laser from the cavity measured at the exit to the cavity.
Claim 6
Dependent Claim
58 words
A cavity configuration for a solid-state laser as defined in claim 3 in which the radius of the concave mirror is approximately 4.7 meters, the radius of the convex mirror is approximately 4 meters and the center of curvature of the concave mirror is approximately 0.3 of a meter from the center of curvature of the convex mirror.
Claim 7
Dependent Claim
51 words
A cavity configuration for a solid-state laser as defined in claim 1 in which both said first and second mirrors are curved, the radius of each mirror is within the range of 1 to 20 meters, and the centers of curvature of the mirrors are within one meter of each other.
Claim 8
Dependent Claim
22 words
A cavity configuration for a solid-state laser as defined in claim 1 in which both the first and second mirrors are concave.
Claim 9
Dependent Claim
22 words
A cavity configuration for a solid-state laser as defined in claim 8 in which both the first and second mirrors are concave.
Claim 10
Dependent Claim
25 words
A cavity configuration for a solid-state laser as defined in claim 1 in which the first mirror is concave and the second mirror is flat.
Claim 11
Dependent Claim
