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.
Claims6
A scalable wavelength beam combiner system comprising:
- a plurality of modular laser input devices, wherein each modular laser input device includes:
- at least one beam emitter configured to produce an electromagnetic beam, and
- at least one transform optic, wherein each transform optic causes the emitted beams to overlap at a dispersive element, and wherein the dispersive element transmits the overlapped beams as a single output profile;
- and
- a partially-reflecting output coupler arranged to receive the combined beams from the dispersive element, to reflect a portion of the combined beams toward the dispersive element, and to transmit the combined beams as a multi-wavelength beam comprising optical radiation having a plurality of wavelengths.

A scalable wavelength beam combiner system comprising:
- a plurality of modular laser input devices, wherein each modular laser input device includes:
- one or more beam emitters 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;
- a dispersive element positioned at a region of overlap of the combined beams to receive and transmit the beams;
- and
- a partially-reflecting output coupler arranged to receive the combined beams from the dispersive element, to reflect a portion of the combined beams toward the dispersive element, and to transmit the combined beams as a multi-wavelength beam comprising optical radiation having a plurality of wavelengths.

- aligning all the received beams parallel to each other;
- combining the parallel beams onto a dispersive element;
- reflecting a portion of the combined beams back into the beam emitters;
- and
- transmitting a single output profile from the dispersive element.
