Nd:YAG laser
Videos
Nd:YAG is a crystal that is used as a lasing medium for solid-state lasers. The dopant, neodymium in the +3 oxidation state, Nd, typically replaces a small fraction of the yttrium ions in the host cry

Ruby laser

A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. The first working laser was a ruby laser made by Theodore H. Maiman at Hughes Research Laboratories on May 16

…two ions are of similar size. It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as the red chromium ion in ruby lasers. Laser operation of Nd:YAG was first demonstrated by Joseph E. Geusic et al. at Bell Laboratories in 1964. Geusic and LeGrand Van Uitert received the…

Ruby laser pistol constructed by Stanford Univ. physics professor in 1964 to demonstrate the laser to his classes. The plastic body recycled from a toy raygun contained a ruby rod between two flashtubes (right). The pulse of coherent red light was strong enough to pop blue balloons (shown at left) but not red balloons which reflected the light.
