Solid state laser materials are commonly made by doping a crystalline solid host with ions that provide the required energy states. For example, the first working laser was a ruby laser, made from ruby (chromium-doped corundum). Formally, the class of solid-state lasers includes ... fiber laser, as the active medium (fiber) is in the solid state. Practically, in the scientific literature, solid-state laser usually means a laser with bulk active medium; while wave-guide lasers are caller fiber lasers.

If you are charging your laser, it is considered common courtesy and safety procedure (as above) to state in a firm and loud voice "IMMA CHARGIN' MAH LAZER!" then shout "IMMA FIRIN' MAH LAZER!" in an even louder voice. Having an accomplice simultaneously shout "SHOOP DA WHOOP" in an equally loud voice can further increase the effectiveness of the warning. Proper pronunciation is discouraged.... Not all lazers come with charging features, so it may be a good idea to either have an expert examine your laser, or to illegally modify it so that it can not only charge, but also have a wider beam, a brighter intensity, shoot through walls, shoot through enemies, and fire from more than one location at a time.

A new high speed pulsing laser developed by Arizona State physics professor Kong-Thon Tsen and his son Shaw-Wei Tsen, a pathology student at Johns Hopkins, has succeeded in killing a common virus without damaging the healthy surrounding cells. The laser utilizes the principle of "forced resonance" by vibrating the shell of a virus to "crack" it. Plus, tests have proven that it is possible to break down the shells at energies far lower than those needed to damage surrounding T-cells. more

Neodymium is a common dopant in various solid state laser crystals, including yttrium orthovanadate (Nd:YVO4), yttrium lithium fluoride (Nd:YLF) and yttrium aluminium garnet (Nd:YAG). All these lasers can produce high powers in the infrared spectrum at 1064 nm. They are used for cutting, welding and marking of metals and other materials, and ... in spectroscopy and for pumping dye lasers. These lasers are also commonly frequency doubled, tripled or quadrupled to produce 532 nm (green, visible), 355 nm (UV) and 266 nm (UV) light when those wavelengths are needed.

To meet its long-term need for precision engagement of high-speed moving targets, the Air Force asked Raytheon to restart the laser-guided Maverick production line after a 15-year hiatus. The latest laser-guided Maverick will incorporate state-of-the-art seeker technology that is expected to improve on Maverick's proven combat record. Raytheon anticipates laser-guided Maverick production for the Air Force, Navy and international customers as early as 2009.
