Speckle Noise Homogenizer (Fiber Optical Beam Stabilization) is an all-fiber passive component which can efficiently homogenize speckle pattern and reduce unwanted modal noise (striations, hot spots, and beam non-uniformity) within a multimode optical fiber, producing a stable output beam that has fewer speckle hot spots and more uniform energy intensity profile. Lfiber’s Fiber Optical Homogenizer (Laser Beam Stabilizers) also mix light, which simplifies the combination of sources. They break up the input beam into smaller beamlets and reconfigure the modes of light. As a result, the input signals are mixed and the output signals are more uniform. The fiber optical speckle reducers offer superior optical transmission over a broad band, typically from 400 nm to 1800 nm. Multimode fibers with 105 μm, 200 μm and 400 μm core diameters are available.
