In a ruby laser, a rod of ruby is irradiated with the intense flash of light from xenon-filled flashtubes. Light in the green and blue regions of the spectrum is absorbed by chromium ions, raising the energy of electrons of the ions from the ground state level to one of the broad F bands of levels. Electrons in the F bands rapidly undergo non-radiative transitions to the two metastable E levels. A non-radiative transition does not result in the emission of light; the energy released in the transition is dissipated as heat in the ruby crystal. 2, record 8, English, - non%2Dradiative%20tansition

La carte exoélectronique d'un échantillon d'aluminium. La surface de l'échantillon est balayée par un faisceau de photons ultraviolets, qui transmettent leur énergie (...) aux électrons du métal et provoquent leur émission. (...) On envoie le faisceau amplifié sur les plaques verticales d'un oscillographe. Si l'on synchronise le balayage du spot ultraviolet et la tension de l'oscilloscope, on obtient sur l'écran la carte exoélectronique de l'échantillon. 2, record 14, French, - exo%C3%A9lectronique
