Special Edition LaserFest Photon Plush Toy

These massless "quanta of light" come in three colors, red, green, and blue. Each photon color represents the wavelength of light produced by a specific type of laser. The first working laser used a synthetic ruby to produce red laser light at 624 nanometers wavelength. The Helium-Cadmium laser produces blue laser light at 442 nanometers wavelength, while the Copper vapor laser produces green laser light at 511 nanometers wavelength.

Come to LaserFest events to get yours, or order one from The Particle Zoo.
