Singular-value decomposition and electromagnetic coherence of optical beams

WebApr 3, 2024 · These beams are directed above the chip to intersect at a central location with diameters > 1 mm. Our design also includes two co-propagating beams at lattice and clock wavelengths. These beams emit colinearly and vertically to probe the center of the magneto-optical trap, where they will have diameters of ≈ 100 µm. WebSpectral beam combining (also called wavelength beam combining or incoherent beam combining) does not require mutual coherence, but rather uses emitters with non-overlapping optical spectra. The single beams are then fed into a wavelength-sensitive beam combiner, such as a prism, a diffraction grating, a dichroic mirror, or a volume Bragg grating.
