Abstract: A system and construction for spot welding either in an industrial environment or for repairing retina detachments in the medical field is disclosed as comprising a fagot-laser system with each individual rod including an output end face whose normal is not colinear to the main axis of the rod. Various patterns can be generated with the arrangement by imaging the near field of the output at the laser rod ends onto the work piece or target at the desired magnification and rearranging or rotating the individual rods. An alternative arrangement is to image the far field onto the work at the desired magnification and to rotate the individual rod elements to achieve pattern variation.

Abstract: Laser light generator containing a glass laser rod with a composition so chosen that the net thermal effects on the index of refraction are negated. The algebraic sum of the effects of the change in index of refraction caused by the temperature coefficient of the index of refraction, the coefficient of linear expansion, Poisson''s ratio and the stress-optical effects, for light in one plane of polarization is chosen to be near zero, while remaining small but negative for the other polarization component.

Abstract: A disc laser structure of all-glass support construction. A segmented neodymium-doped glass laser rod is supported in a glass tubing and is designed to permit fluid coolant flow within the tubing and amongst the rod segments. The non-laserable glass supporting means consists of samarium-doped cladding glass to reduce interference by ''''off axis'''' spontaneously emitted light. The fluid coolant has an index of refraction which matches that of the laser glass to achieve a high efficiency. The absence of metallic supporting means minimizes the chance of metallic decomposition under the influence of pump light. Compensation for a radial refractive index gradient is provided by figuring (creating a non-zero optical power in) one or more of the glass discs.

Abstract: A laser system is disclosed as including a conventional laser generator in tandem and in optical alignment with a laser amplifier, the laser amplifier having a series of laser disks disposed in parallel array in a laser cavity with a coolant therein. The laser disks are arranged as amplifier input disks and amplifier output disks with the input disks using trivalent neodymium as the active ingredient and the output disks using a combination of trivalent neodymium and trivalent ytterbium as the active laser material.

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.

Abstract: A multiple wavelength optical isolator provides isolation for the light characteristic of either a neodymium glass laser, 1.06 Mu m., or ruby, 0.6943 Mu m. by immersion in either liquid nitrogen or the combination of dry ice and acetone respectively. The isolator includes a piece of silicate glass doped with 58 weight percent of terbium oxide which is subjected to the field of a permanent magnet of approximately 1100 gauss parallel to the path of light in the glass. The thickness of glass in this dimension is approximately 7.7 cm.

Abstract: Solid optical materials such as glass which are to be used in laser systems may fail catastrophically due to the presence of microinhomogeneities. These microinhomogeneities are locatable by exposing the material to a laser pulse which preferably has a pulse duration of approximately 0.1 to 10 microseconds.
