Webshot noise: [noun] a sputtering or popping produced (as in a radio) by shot effect. WebIn a quantum optical system shot noise is the noise due to counting photons at the output of the detector while back action noise is due to the photons imparting momentum to the mirrors in the system. Both arise from the statistical nature of quantum mechanics. WebShot-noise-limited laser operation over a wide spectral bandwidth is demonstrated by using a semiconductor active medium inserted into a high- Q external cavity. This approach ensures, with a compact design, a sufficiently long photon lifetime to reach the oscillation-relaxation-free class A regime. how far is bolton abbey from blackpool
