Photonics Dictionary: P

A gas made up of electrons and ions.

A plasma accelerator is a type of particle accelerator that uses electric fields and magnetic fields to accelerate charged particles, typically electrons or ions, by exploiting the motion of charged...

The use of a plasma to induce the formation of oxides in the production of graded-index optical fibers.

A type of flat panel display made up of a layer of gas between two glass plates. The glass is coated with parallel conductors that form cells which, when energized, produce a gas discharge that makes...

Operates with light collectively emitted by the recombination of free electrons and ions in the plasma state.

Introduced into the laser beam from localized fluctuations in current density within the plasma itself. These fluctuations represent macroscopic changes of gain in the laser.

The study of highly ionized gases. Many phenomena not exhibited by uncharged gases are associated with plasma physics.

Plasma's ability to stop the transmission of laser light.

An electron beam gun in which plasma that is generated within a low-voltage hollow-cathode discharge serves as the source of electrons.

Monolithic self-scanning linear image sensor array for multichannel spectroscopy with a spectral range of from 200 to 1000 nm.

The use of a reflective device, which can be fashioned from a variety of materials including gases, solids, dyes, aerosols, semiconductor crystals and plasmas, to replicate a laser beam by reversing...
