摘要:
In various embodiments, wavelength beam combining laser systems incorporate optical cross-coupling mitigation systems and/or engineered partially reflective output couplers in order to reduce or substantially eliminate unwanted back-reflection of stray light.
摘要:
In various embodiments, a beam-parameter adjustment system and focusing system alters a spatial power distribution of a radiation beams before the beam is coupled into an optical fiber or delivered to a workpiece.
摘要:
In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.
摘要:
In various embodiments, one or more prisms are utilized in a wavelength beam combining laser system to regulate beam size and/or to provide narrower wavelength bandwidth.
摘要:
In various embodiments, a wavelength beam combining laser system includes a fast-axis collimation lens that is rotated with respect to a plurality of emitters in order to converge the emitted beams onto a dispersive element and/or reduce the size of the multi- wavelength output beam of the system.
摘要:
A system and method for reconfiguring a plurality of electromagnetic beams to take advantage of various wavelength beam combining techniques. The reconfiguring of beams includes individual rotation and selective repositioning of one or more beams with respect to beam's original input position.
摘要:
In various embodiments, the beam parameter product and/or beam shape of a laser beam is adjusted by coupling the laser beam into an optical fiber of a fiber bundle and directing the laser beam onto one or more in-coupling locations on the input end of the optical fiber. The beam emitted at the output end of the optical fiber may be utilized to process a workpiece.
摘要:
In various embodiments, workpieces are processed, e.g., via welding or cutting, while the shape and/or one or more other parameters of the laser processing beam are altered. The shape and/or one or more other parameters of the laser processing beam may be varied based on one or more characteristics of the workpiece.
