Abstract
Abstract A metal vapour laser which can produce two or more discrete outputs from a single vacuum chamber. This is achieved by using two or more different materials and by confining each material to its own area so that the materials do not mix one with the other and optimum lasing performance can be obtained from each material. All the lasing areas have a common optical axis. The lasing outputs can be produced separately or mixed together as required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A laser device capable of producing lasing output from at least two materials, each of which requires different conditions to produce optimum stimulated emission or which is a material whose lasing performance is less than the optimum in the presence of another material, the laser device comprising a vacuum chamber characterised in that a separate region is provided within said chamber for each material, all said regions having a common optical axis, means for confining each material to its own region and means for producing in each region the appropriate conditions for stimulated emission.
Claim 2
Dependent Claim
94 words
A laser device capable of producing lasing output from at least two materials, each of which requires different conditions to produce optimum stimulated emission or which is a material whose lasing performance is less than the optimum in the presence of another material, the laser device comprising a vacuum chamber characterised in that a separate region is provided within said chamber for each material, all said regions having a common optical axis, means for confining each material to its own region and means for producing in each region the appropriate conditions for stimulated emission.
Claim 3
Dependent Claim
22 words
A laser devised as claimed in claim 1, characterised in that adjacent regions are separated by a cool zone within said chamber.
Claim 4
Dependent Claim
29 words
A laser device as claimed in claim 2, characterised in that each cool zone is formed by an area of increased heat loss along the length of said chamber.
Claim 5
Dependent Claim
26 words
A laser device as claimed in claim 3, characterised by insulation surrounding said chamber wherein said area of increased heat loss is formed by reduced insulation.
Claim 6
Dependent Claim
37 words
A laser device as claimed in any one of claims 1 to 4, characterised in that each separate region has different thermal loss properties to assist in producing in each region said appropriate conditions for stimulated emission.
Claim 7
Dependent Claim
32 words
6 A laser device as claimed in any one of claims 1 to 5, characterised in that means are provided to produce lasing emissions from more than one region, to be combined.
