Abstract
A multiple density layered insulator for use with a laser is disclosed wh provides at least two different insulation materials for a laser discharge tube, where the two insulation materials have different thermoconductivities. The multiple layer insulation materials provide for improved thermoconductivity capability for improved laser operation.
Claims5
In a metal vapor laser comprising a housing for the laser discharge chamber, the improvement comprising insulation materials annularly surrounding the exterior of said housing, said materials comprising an inner layer contiguous to said housing of a first insulating material, and an outer layer contiguous to said inner layer comprising a second insulating material, said first insulating material selected from the group consisting of aluminum powder and zirconia, and said second insulating material selected from the group consisting of aluminum fiber and metal foil, respectively, wherein the respective thicknesses of each of said layers are such that when the temperature of said housing is 1600.degree. C., the maximum temperature within said layers is no greater than 1600.degree. C.
