摘要： Techniques and architecture are disclosed for providing a laser system. In one specific example embodiment, the system includes a thulium-doped fiber laser coupled by silica glass fiber to a remote optical converter (ROC) including a Ho:YAG laser and, optionally, an optical parametric oscillator (OPO) utilizing zinc germanium phosphide (ZnGeP2; ZGP) or orientation-patterned gallium arsenide (OPGaAs). The fiber laser may emit a low-peak-power, continuous wave pump signal that pumps the Ho:YAG laser, which in turn emits a higher-peak-power, pulsed signal. When included, the OPO can be used to convert the resultant, pulsed signal to a longer wavelength (e.g., about 2-5 μm, or greater). In some cases, distributed architecture and reduced weight/bulk may be realized while eliminating the need to actively cool the ROC for operation, for example, over a broad temperature range (e.g., −55-125° C.). Also, methods of preparing high-peak-power, pulsed signals using such systems are disclosed.

摘要： A method and apparatus for laser beam splitting and shaping is disclosed wherein two beam splitters are used to split one input laser beam into four beams in a generally rectangular pattern. Half-wave plates are used to adjust the power of the input laser beam between the four laser beams. A variable power optical telescope comprising negative and positive lens pairs for the four laser beams is used to adjust the divergence of the four beams, and pointing control prism wedges are used to point or steer the four beams to be parallel to each other and to adjust their relative spacing to create a flat top profile.

摘要： A system and method for scanning a wide band beam is presented. An apparatus includes a pair of prism triplets. Each prism triplet includes a first wedge prism, a second wedge prism and a third wedge prism all formed with different optical materials. In operation, a beam passing through the wide band team scanning apparatus first passes through the first, second and third wedge prisms of the first prism triplet. The beam then passes through the wedge prisms of the second prism triplet in a mirrored order (the third, then second, then first wedge prisms) than that of the first prism triplet. This apparatus with two prism triplets allows wide band light transmitted through it to emerge with its plurality of different wavelengths of light travelling in the same direction to equalize net dispersive effects each of different wavelengths.

摘要： The instant invention is directed in general to optical systems in which a laser beam is injected into the end of an optical fiber and, more specifically, to laser materials processing systems in which a high power laser beam is injected into the fiber input end for transmission to a remote end of the fiber where materials processing is performed with the emitted beam. In a preferred embodiment of the instant invention, an injection chamber is used to isolate the optical fiber injection end from the surrounding air by enclosing the optical fiber injection end, and providing a gas purge to reduce the air concentration and to keep dust from entering or settling on the optical fiber injection end. This preferred embodiment prevents the ionization of the air surrounding the fiber injection end, thereby preventing the damaging effects of ionization which often occur during optical fiber injection processes.
