Abstract
Abstract This application relates to a gas laser structure having an insulating, heat resistant discharge tube having means associated therewith for transferring heat therefrom during lasing operation. In a first embodiment, cooling fins are attached to the outer surface of the discharge tube. In further embodiments, the fins extend through the outer discharge tube wall and are either formed to provide, among the plurality of fins, an inner discharge tube or are connected to substantially cylindrical discharge tube sections. In still a further embodiment, a boilercondenser--vapor cooling technique structure is disclosed. Means to equalize the pressure between the opposite ends of the laser structure is also disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
234 words
An ionized gas laser structure comprising: an outer cylindrically shaped tube; a plurality of metal fins mounted on and spaced along the length of said outer tube and intimate contact with the surface thereof; a pair of hollow cylindrically shaped members respectively mounted on and enclosing the ends of said outer tube, each of said members having a pair of apertures therethrough within the space circumscribed by said outer tube, the apertures of one member facing and in registration with the apertures of the other member; a discharge tube mounted inside said outer tube between one pair of said apertures that are in registration with each other, whereby said discharge tube couples at opposite ends thereof with the chambers formed by said members; a pressure-equalizing tube mounted inside said outer tube between the other pair of said apertures that are in registration with each other, whereby said pressure-equalizing tube couples at opposite ends thereof with the chambers formed by said members, said pressure-equalizing tube being positioned above said discharge tube; a coolant fluid contained within said outer tube to a level that covers said discharge tube, said pressure-equalizing tube being above the level of said coolant fluid; a gas capable of lasing contained within said discharge and pressure-equalizing tubes and the hollows of said members; and electro-optical laser means respectively mounted in and on said members to produce a lasing action of said gas.
Claim 2
Dependent Claim
234 words
An ionized gas laser structure comprising: an outer cylindrically shaped tube; a plurality of metal fins mounted on and spaced along the length of said outer tube and intimate contact with the surface thereof; a pair of hollow cylindrically shaped members respectively mounted on and enclosing the ends of said outer tube, each of said members having a pair of apertures therethrough within the space circumscribed by said outer tube, the apertures of one member facing and in registration with the apertures of the other member; a discharge tube mounted inside said outer tube between one pair of said apertures that are in registration with each other, whereby said discharge tube couples at opposite ends thereof with the chambers formed by said members; a pressure-equalizing tube mounted inside said outer tube between the other pair of said apertures that are in registration with each other, whereby said pressure-equalizing tube couples at opposite ends thereof with the chambers formed by said members, said pressure-equalizing tube being positioned above said discharge tube; a coolant fluid contained within said outer tube to a level that covers said discharge tube, said pressure-equalizing tube being above the level of said coolant fluid; a gas capable of lasing contained within said discharge and pressure-equalizing tubes and the hollows of said members; and electro-optical laser means respectively mounted in and on said members to produce a lasing action of said gas.
Claim 3
Dependent Claim
51 words
The structure defined in claim 1 wherein said structure further includes means mounted at one end of said discharge tube to permit said discharge tube to expand and contract in response to temperature variations and at the same time hermetically sealing said end of the discharge tube to its associated member.
Claim 4
Dependent Claim
27 words
The structure defined in claim 1 wherein said outer tube and said pressure-equalizing tube are each made of metal sections that are electrically insulated from one another.
