Visitors can choose between the three phenomena and see the various states that excited electrons pass through in returning to the ground state. http://www.merlot.org/merlot/viewMaterial.htm?id=89431 This tutorial explores how a ruby laser crystal works when excited by a xenon flash tube. As photon energy is "pumped" into the crystal by the flash tube, the internal crystal photons reflect on the mirrored ends of the crystal until they have achieved enough energy to escape in the form of a laser beam. http://www.merlot.org/merlot/viewMaterial.htm?id=647942 A group of simulations on the physical and geometric nature of light along with applications of electromagnetic radiation.
