Laser and ruby rod. Experiment with a green laser beam being used to induce red luminescence in a rod of artificial ruby. The laser beam is also passing through a liquid in which the rod is partially submerged. Synthetic ruby is used to make ruby lasers, where green laser light is absorbed and re-emitted as red laser light.
