摘要： A laser includes a laser source and an power source arranged such that both components have substantially the same cross-section, with cooling fins arranged axially along the length of each element. The components are arranged end-to-end in a series to form an assembly with substantially the same cross-section along the entire length of the assembly. A shroud mounted along the assembly forms a single air channel directing air from a fan along the entire length of the assembly, for cooling both the power source and the laser source with the total air flow from the at least one fan. The laser source and the power source are arranged in series such that the laser source is cooled first, and the subsequent air flow, although slightly warmer from cooling the laser source, is sufficient to cool the power source.

摘要： Slab lasers and method for producing high power coherent laser radiation of good quality. In one embodiment, a slab laser comprises a slab laser medium, an energy source configured to deliver energy to the laser medium, and first and second optical elements. The first optical element has a first reflective surface at a first boundary of the laser medium, and the second optical element has a second reflective surface at a second boundary of the laser medium. The first and second reflective surfaces face each other across the length of the laser medium, and at least one of the first and second optical elements includes a plurality of reflective regions configured to modify the phase distribution of the incident laser radiation propagating from the reflective regions. The first and second reflective surfaces are also positioned at an angle relative to each other to form a laser resonator.

摘要： A laser safety enclosure structure has an outer enclosure made of a formable material with a limited ability to withstand exposure to a laser beam and an inner enclosure composed of a laser beam blocking material capable of indefinitely withstanding exposure to a laser beam of a given wavelength and power level so as to prevent such a laser beam incident on the blocking material from escaping the inner enclosure.

摘要： Laser-based material processing systems and methods for using such systems are disclosed herein. In one embodiment, for example, a laser-based material processing system includes a workpiece support, a positioning assembly over at least a portion of the workpiece support, and a laser. The system includes a laser beam director carried by the positioning assembly to direct a beam generated by the laser toward the workpiece support. The system also includes a dispensing unit carried by the positioning assembly to discharge a material toward the workpiece support. The system further includes a controller operably coupled to the positioning assembly, the laser beam director, and the dispensing unit. The controller can be configured to move the laser beam director and the dispensing unit relative to the workpiece support such that (a) the beam is directed toward a first portion of the workpiece support, and (b) the dispensing unit discharges material toward the first portion of the workpiece support.

摘要： A source of pulsed multicolor coherent light, usable for holographic purposes, comprises two lasers emitting wavelengths of 694 nm and 1064 nm, respectively. The emissions of these lasers are passed jointly through a nonlinear optical element such as an LiIO.sub.3 or KDP crystal, acting as a mixer, and are then partly deviated through a similar element serving as a frequency doubler. The mixer emits a wavelength of 420 nm in the blue region of the spectrum; the wavelength of 694 nm lies in the red region, whereas the wavelength of 1064 nm is transformed by the frequency doubler to 532 nm in the green region.
