Distinguishing Between Incoherent and Coherent Light

WebAug 29, 2024 · The incoherent beam was obtained by increasing the number of modes constituting the output beam of the seed laser. This increase was obtained by removing the intra–cavity aperture from the seed laser and simultaneously increasing the pump power. WebMar 1, 2024 · A common way of reducing the spatial coherence of a laser is to generate many speckle patterns with a time-varying scattering system and then sum the intensities. Even though each speckle pattern has a contrast of unity, an incoherent sum of N uncorrelated speckle patterns reduces the speckle contrast by a factor of N1/2.
