WebAn optical beam is said to be self-healing when, distorted by an obstacle, the beam corrects itself upon propagation. In this Letter we show, through experiments supported by numerical simulations, that Helico-conical optical beams self-heal. We observe the strong resilience of these beams with different types of obstructions, and relate this to the characteristics of … 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.
