**Coherent anti-Stokes Raman spectroscopy** — Coherent anti Stokes Raman spectroscopy, also called Coherent anti Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures… … Wikipedia

**Coherent states in mathematical physics** — Coherent states have been introduced in a physical context, first as quasi classical states in quantum mechanics, then as the backbone of quantum optics and they are described in that spirit in the article Coherent states (see also [1]). However … Wikipedia

**Coherent states** — In quantum mechanics a coherent state is a specific kind of quantum state of the quantum harmonic oscillator whose dynamics most closely resembles the oscillating behaviour of a classical harmonic oscillator. It was the first example of quantum… … Wikipedia

**Coherent state** — In quantum mechanics a coherent state is a specific kind of quantum state of the quantum harmonic oscillator whose dynamics most closely resemble the oscillating behaviour of a classical harmonic oscillator system. It was the first example of… … Wikipedia

**Squeezed coherent state** — In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value::Delta x Delta p =… … Wikipedia

**Optical parametric oscillator** — Infrared optical parametric oscillator An optical parametric oscillator (OPO) is a parametric oscillator which oscillates at optical frequencies. It converts an input laser wave (called pump ) into two output waves of lower frequency (ωs,ωi) by… … Wikipedia

**Quantum harmonic oscillator** — The quantum harmonic oscillator is the quantum mechanical analogue of the classical harmonic oscillator. It is one of the most important model systems in quantum mechanics because an arbitrary potential can be approximated as a harmonic potential … Wikipedia

**Tesla's oscillator** — is a mechanical oscillator conceived of and invented by Nikola Tesla in 1898. It is also referred to as the Earthquake Machine. The machine which Tesla tested was small, around seven inches long, and weighing only one or two pounds; something you … Wikipedia

**Multiple-prism grating laser oscillator** — Multiple prism grating laser oscillators,[1] or MPG laser oscillators, use multiple prism beam expansion to illuminate a diffraction grating mounted either in Littrow configuration or grazing incidence configuration. Originally, these narrow… … Wikipedia

**Opto-electronic oscillator** — An opto electronic oscillator (OEO) is an optoelectronic circuit that produces repetitive electronic sine wave and/or modulated optical continuous wave signals. An opto electronic oscillator is based on converting the continuous light energy from … Wikipedia
