Folded optics refers to a design technique in optical systems where light paths are altered using reflective surfaces to "fold" the optical path. This is commonly achieved using mirrors, prisms, or other optical components that redirect light, allowing for more compact designs and enabling various applications in optical devices. This technique is particularly useful in several areas: 1. **Compact Design**: By folding the optical path, systems can fit into smaller spaces while maintaining the necessary optical performance.
**Laser Physics** is a peer-reviewed scientific journal that focuses on the field of laser science and technology. The journal publishes research articles, reviews, and other scholarly contributions that advance the understanding of lasers and their applications in various domains, including physics, engineering, and materials science.
Lasing without inversion (LWI) is a phenomenon in quantum optics that refers to a mechanism of producing coherent light (laser light) in a system where the usual requirement for population inversion is not met. Normally, in traditional laser operation, a population inversion is necessary, where more atoms or molecules are in an excited state than in a lower energy state. This population inversion is essential for achieving stimulated emission, the fundamental process that amplifies light in a laser.
A lenslet is a small lens that is typically used in optical systems such as plenoptic cameras, light field sensors, and displays. Lenslets are part of arrays of lenses that help capture or manipulate light in specific ways, enabling features like depth sensing and 3D imaging. In the context of light field technology, for example, lenslets are arranged to capture multiple perspectives of a scene simultaneously. This allows for post-capture changes in focus or perspective.
Borel–de Siebenthal theory is a mathematical framework primarily associated with the study of compact Lie groups and their representations, particularly in the context of algebraic groups and symmetric spaces. The theory deals with the classification of maximal connected solvable subgroups, or Borel subgroups, in the context of semisimple Lie groups. It extends concepts of Borel subgroups from the language of algebraic groups to that of Lie groups.
A group is said to be diagonalizable if it can be represented in a certain way with respect to its action on a vector space, particularly in the context of linear algebra. More specifically, in the context of linear representations, a group is diagonalizable when its representation can be expressed in a diagonal form. In this context, consider a group \( G \) acting on a vector space \( V \) over some field, typically the complex numbers.

Live MOS (Metal-Oxide-Semiconductor) is a type of image sensor technology primarily used in digital cameras and camcorders. Developed by Panasonic, Live MOS sensors combine the advantages of both CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor) technologies.
The Lummer-Gehrcke interferometer is a type of optical device used for precise measurements of wavelengths and other optical properties. It operates based on the principle of interference and utilizes thin film optics. The device typically comprises two highly reflective mirrors separated by a thin air gap or a thin film, creating a set of parallel surfaces.
A Lyot stop is a specific optical element used in various types of imaging systems, particularly in the context of astronomical telescopes and spectrometers. Named after the French physicist Paul Lyot, it functions as a spatial filter to improve the quality of the light that passes through by blocking unwanted portions of the light wavefront. In practical terms, the Lyot stop is typically placed at or near the focal plane of the telescope or optical system.
Refractive index contrast refers to the difference in the refractive indices between two or more materials. The refractive index is a measure of how much light is bent or refracted when it enters a material. It is defined as the ratio of the speed of light in a vacuum to the speed of light in a specific medium. In many optical applications, the contrast in refractive indices is critical for phenomena such as reflection, refraction, and optical waveguiding.

Intrinsic hyperpolarizability refers to a property of nonlinear optical materials, specifically in the context of their response to external electric fields. It quantifies how the polarization of a material changes in response to the electric field beyond the linear approximation. While the linear response of a medium to an electric field can be described by its linear polarizability, hyperpolarizability is the next level in the series expansion of the polarization with respect to the electric field.
