Abstract
Abstract An optical maser or laser structure is provided with a segmented laser rod and is immersed in a coolant fluid for maintaining the operating temperature of the laser rod segments at a substantially uniform temperature. The segmented structure is formed of menisci-shaped segments of zero lens power, spaced apart a sufficient distance to permit free passage of sufficient coolant for temperature maintenance but close enough to prevent pump light from passing through the spaces between the segments.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
In the laser structure of claim 1, said laser rod is comprised of a series of plates each of which has a convex face and a concave face generally normal to the longitudinal axis with said faces being substantially parallel along their curves to provide a substantially uniform thickness of plate having a zero lens power; one end plate of said series having a planar, outside face and an inner, convex face and the opposite end plate having a planar outside face and an inner concave face, and in combination, the spacings and opposed sequential faces prevent light rays from passing between adjacent plates from one side of the structure to the other without impingement upon at least one of the plates of the series.
Claim 2
Dependent Claim
25 words
A laser structure according to claim 2 wherein the distance between said plates is approximate one-tenth the thickness of the plates intermediate said end plates.
Claim 3
Dependent Claim
31 words
A laser structure according to claim 2 wherein said planar surfaces on said end plates are mirrored to reflect light, and one said mirrored surface is arranged to be slightly transmissive.
Claim 4
Dependent Claim
13 words
A laser structure according to claim 2 wherein said plates are meniscus shaped.
Claim 5
Dependent Claim
17 words
A laser structure according to claim 2 wherein said plates between said end plates are substantially identical.
