These methods were developed to increase overall source “brightness.”. Both techniques increase the output power as the number of beams, N, and increase the far-field peak intensity as N 2. 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. how many opportunities does college open
