How is the coherence time related to the duration of the wave packet? What is the spectral purity of a coherent light source?

One of the important parameters of illumination sources is their coherence, which is somewhat related to brightness due to the fact that extremely bright ... Jun 27, 2022 ... Consider three equally spaced and equal-intensity coherent sources of light (such as adding a third slit to the two slits). Use the phasor method to obtain the ... Coherent light sources from visible to near-infrared wavelengths have driven innovative developments, impacting various domains (telecommunications, ... Feb 16, 2023 ... We analyze three non-stationary partially coherent sources whose coherent modes are spatiotemporal optical vortex (STOV) beams. ... light) to ... Lasers & Light Sources; Optomechanics; Fiber Optics; Detection Devices; Electro-Optics & Electronics; Machines; Imaging & Microscopy; Design Software; Raw ... We demonstrate a new optical technique that converts light from a sparse array of mutually coherent sources into a single-lobed far-field with a theoretical ... For light waves, lasers are often used because they emit light that is not only monochromatic (of a single wavelength) but also coherent. For sound waves, ... Sep 1, 2010 ... In some situations, a major problem with coherent sources such as laser diodes is speckle, which may have to be removed prior to ... Law of wave interference from two coherent sources. Depending on the phase difference two waves are added constructively or destructively. An optical multimode fiber as pseudothermal light source. Article 20 June 2017.
