Abstract: A side of a polygonal cross-sectioned glass laser rod core may be clad by applying a slab of a suitable cladding glass material thereto. The fusing of the slab to the core without the formation of entrapped gas bubbles therebetween is accomplished by allowing the slab to rest in essentially line contact with the side of the core at the end adjacent a suitable drawing furnace. The other end of the slab is spaced away from the core material. Means is provided for urging the slab of cladding material toward the side of the encore such that as the core and cladding material are drawn within the drawing furnace, the line of contact between the core and cladding gradually traverses the length of the core and cladding thereby forcing any gas out of the space which exists between the core and cladding to provide a bubble-free interface in the resulting clad glass laser rod.

Abstract: A SIDE OF A POLYGONAL CROSS-SECTIONED GLASS LASER ROD CORE MAY BE CLAD BY APPLYING A SLAB OF A SUITABLE CLADDING GLASS MATERIAL THERETO. THE FUSING OF THE SLAB TO THE CORE WITHOUT THE FORMATION OF ENTRAPPED GAS BUBBLES THEREBETWEEN IS ACCOMPLISHED BY ALLOWING THE SLAB TO REST IN ESSENTIALLY LINE CONTACT WITH THE SIDE OF THE CORE AT THE END ADJACENT A SUITABLE DRAWING FURNACE. THE OTHER END OF THE SLAB IS SPACED AWAY FROM THE CORE MATERIAL. MEANS IS PROVIDED FOR URGING THE SLAB OF CLADDING MATERIAL TOWARD THE SIDE OF THE CORE SUCH THAT AS THE CORE AND CLADDING METERIAL ARE DRAWN WITHIN THE DRAWING FURNACE, THE LINE OF CONTACT BETWEEN THE CORE AND CLADDING GRADUALLY TRAVERSES THE LENGTH OF THE CORE AND CLADDING THEREBY FORCING ANY GAS OUT OF THE SPACE WHICH EXISTS BETWEEN THE CORE AND CLADDING TO PROVIDE A BUBBLE-FREE INTERFACE IN THE RESULTING CLAD GLASS LASER ROD.
