cooling cylinder click to hear : cooling cylinder

Casing in which water generally circulates to cool the ruby cylinder, which becomes very hot as it produces the beam.

fully reflecting mirror click to hear : fully reflecting mirror

Reflects all the light energy toward the partially reflecting mirror. The reflection between the mirrors intensifies the light to form a highly concentrated beam.

reflecting cylinder click to hear : reflecting cylinder

Laser’s metal casing whose inside is polished so that it reflects the light toward the ruby cylinder.

flash tube click to hear : flash tube

Lamp that acts as an energy source by emitting a flash of white light, which excites the ruby atoms and causes them to emit photons.

partially reflecting mirror click to hear : partially reflecting mirror

Its partial transparency allows light beams to escape.

photon click to hear : photon

Energy particle that emits the ruby-chromium atoms as they are excited by flashes in the tube.

ruby cylinder click to hear : ruby cylinder

Ruby bar (crystallized alumina) that contains chromium atoms. It has mirrors at each end, which form the amplification medium to produce the laser beam.
