This process requires the active medium to be pumped either electrically or optically.
This process requires the active medium to be pumped either electrically or optically. Each photon pumped into the medium triggers more photons identical to the trigger photon to be released by the atoms. The released photons cause a chain reaction among the atoms, releasing more photons, leading to a huge number of identical photons to be released in a beam of light. FTP, name this process by which a concentrated beam of light is generated by an active medium working to amplify photons.          |
