    摘要： A high power source of electro-magnetic radiation having a multi-purpose housing is disclosed. The multi-purpose housing includes an interior filled with a material forming at least a light source and further comprising a reflector which can envelope a laser rod surrounded by light sources for providing light excitation to the laser rod. A material defining outer surfaces of the light sources extends out to and defines outer surfaces of the reflector. A high-reflectivity coating is disposed over an outer surface of the reflector, as is a protective coating. Also disposed over an outer surface of the reflector can be an optional heat sink, with cooling being performed by an optional arrangement of forced-air traveling over the heat sink. The light sources may be light source pumps, and the high-reflectivity coating may be formed to envelop the reflector.

    摘要： Laser apparatus configured to minimize wavefront distortion of a coherent light beam is disclosed. The lasing medium (102) of the laser apparatus has a hexagonal cross section and an internal surface (112) with a circular cross section (116) coaxial with a longitudinal axis of the lasing medium. The internal surface defines an interior space (116) for receiving an optical pumping source (114). The external faces (110) of the lasing medium are surrounded with a circumferential reflector (122) and fluid coolant is flowed over the internal surface and external faces. The coherent light beam is passed through the lasing medium to follow a helical course totally internally reflecting off of the external faces.

The inventive laser includes an annular gain medium (37); a source of pump energy (13,15,17); and an arrangement for concentrating energy from the source (13,15,17) on the gain medium (37). In a more specific implementation, a mechanism is included for rotating the gain medium (37) to effect extraction of pump energy and cooling. In the illustrative embodiment, the pump source is a diode array (13,15,17). Energy from the array (13,15,17) is coupled to the medium (37) via an array of optical fibers (25,27,29). The outputs of the fibers (25,27,29) are input to a concentrator (31) that directs the pump energy onto a pump region of the medium (37). In the best mode, plural disks of gain media (37) are arranged in an offset manner to provide a single resonator architecture. First and second mirrors (48,49) are added to complete the resonator, in accordance with the inventive teachings, a method for pumping and cooling a laser is taught. In the illustrative embodiment, the inventive method includes the steps of providing a gain medium (37); pumping energy into a region of the gain medium (37); moving the medium (37); extracting energy from the region of the medium (37); and cooling region of the medium (37).

    摘要： A compact, light weight laser beam combiner (10;110) includes a pair of concentric annular shells (12;112) defining an annular cavity (14;114) of an annular ring resonator having an annular solid laser gain medium (20;120) disposed therein. The output ends of a plurality of low power and brightness fiber lasers (22;122) are coupled into the cavity (14;114) of the resonator such that fiber laser beams cause the gain medium (20;120) in the resonator cavity to lase and produce an annular beam of laser light. Optical elements (16,18;116,118) of the resonator are operable to feed a first portion of the laser light back through the resonator cavity (14;114) to support regenerative lasing of the laser medium (20;120) and to couple off a second portion of the laser light in the form of a circular beam of high power and high brightness laser light. A fluid may be circulated through the resonator cavity to cool the laser medium.

The tube (108) may include two identically loaded laser gain elements (108a) separated by a 90 degree toric quartz rotator (118) and optically transparent endcaps (106) . The laser may comprise axicon, waxicon or reflaxicon optics (103) to convert the annular beam to a compacted cylindrical beam. Plural amplifier modules (220) may be concatenated. Advantageously, thermal lensing effects, birefringence, bifocussing, and alignment problems associated with typical tube SSLs are eliminated or reduced while providing high beam quality and high average power levels.
