Abstract
Systems and methods have been provided to increase output power, as well as spatial and/or spectral brightness when utilizing or combining a plurality of laser elements.
Claims8
A scalable wavelength beam combiner system comprising:
- a plurality of modular laser input devices, wherein each modular laser input device includes:
- at least one laser element configured to produce an electromagnetic beam, and
- at least one transform optic, wherein each transform optic causes the emitted beams overlap at a dispersive element, and wherein the dispersive element transmits the overlapped beams as a single output profile.
A scalable wavelength beam combiner system comprising:
- a plurality of modular laser input devices, wherein each modular laser input device includes:
- one or more laser elements each configured to produce an electromagnetic beam, and
- at least one primary telescoping optic configured to receive the beams;
- a secondary telescoping optic aligned to form a telescoping system with each of the primary telescoping optics, wherein the telescoping system aligns the beams parallel to each other;
- a transform optic configured to receive the parallel beams and combine the parallel beams along a beam combining dimension;
- and
- a dispersive element positioned at a region of overlap of the combined beams to receive and transmit the beams, wherein an output profile is formed.

A method for scaling a WBC system comprising the steps of:
- arranging a plurality of transform optics to each receive and overlap at least one emitted electromagnetic beam onto a dispersive element;
- and
- transmitting a single output profile from the overlapped beams.
A method for a scaling a WBC system comprising the steps of:
- receiving emitted electromagnetic beams from modules of one or more laser elements into an optical telescoping system having more than one input surface, wherein the telescoping system has an input surface for each module;
- aligning all the received beams parallel to each other;
- overlapping the parallel beams onto a dispersive element;
- and
- transmitting a single output profile from the dispersive element.
