Source: Wikipedia Gaussian Optics Gaussian Optics Overview Gaussian optics is a framework used to describe optical phenomena, primarily based on geometrical optics and the paraxial approximation. It was developed by Johann Carl Friedrich Gauss and remains widely utilized in various optical systems. Key Assumptions Utilization of rays around an optical axis and the paraxial approximation. […]
Source: Gamdan Optics Spatial Walk-Off in Photonics Understanding Spatial Walk-Off Spatial walk-off is a phenomenon that occurs in anisotropic crystals, where the intensity distribution of a laser beam can drift away from the direction defined by the wave vector. This is due to the finite angle between the Poynting vector (which indicates the direction of
Source: Wikipedia Understanding Wavenumber in Physics Wavenumber in Physics In general physics, the wavenumber of light is commonly defined as the magnitude of the wave vector, representing the phase delay per unit length during propagation of a plane wave. For light traveling in a medium, the wavenumber is calculated by multiplying the vacuum wavenumber by

They represent the spatial distribution of the wave’s phase at a given instant in time. In simpler terms, wavefronts show where the wave is at the same point in its cycle. Types
