pulse shape
21Self-phase modulation — (SPM) is a nonlinear optical effect of light matter interaction.An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. This variation in refractive index… …
22National Ignition Facility — NIF s basic layout. The laser pulse is generated in the room just right of center, and is sent into the beamlines (blue) on either side. After several passes through the beamlines the light is sent into the switchyard (red) where it is aimed into …
23Scintillator — Scintillation crystal surrounded by various scintillation detector assemblies …
24Microchannel plate detector — from the Daresbury Recoil Separator A micro channel plate (MCP) is a planar component used for detection of particles (electrons or ions) and impinging radiation (ultraviolet radiation and X rays). It is closely related to an electron multiplier …
25Multivibrator — A multivibrator is an electronic circuit used to implement a variety of simple two state systems such as oscillators, timers and flip flops. It is characterized by two amplifying devices (transistors, electron tubes or other devices) cross… …
26C-UWB — is an acronym for Continuous Pulse Ultra wideband technology. C UWB derives its UWB bandwidth by virtue of the short time duration of the individual pulses. Information can be imparted (modulated) on UWB signals (pulses) by encoding the polarity… …
27Pêche électrique — L expression pêche électrique ou électropêche (Electrofishing pour les anglophones) désigne tous les moyens de pêcher des organismes aquatiques (poissons en général) au moyen d un courant électrique. Exemple d électropêche sur petit cours d eau… …
28Scintillation (physics) — Scintillation is a flash of light produced in a transparent material by an ionization event. See scintillator and scintillation counter for practical applications.OverviewThe process of scintillation is one of luminescence whereby light of a… …
29Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… …
30Spatial light modulator — A spatial light modulator (SLM) is an object that imposes some form of spatially varying modulation on a beam of light. A simple example is an overhead projector transparency. Usually when the phrase SLM is used, it means that the transparency… …
