I have a cheap pen/laser pointer which cost $1.99. My friend still insists that inside of this and all others a diamond or possibly another gem is present. Thank You for your help.I believe that modern science has created an alternative, cheaper, and more practical methods to producing such laser/pen pointers. Such as the use of synthetics or other manufactured material.
 
In chemistry I learned it was RUBY (not just any gem stone) and a flashtube which creates a laser.
 
Lasers are made by electromagnetic radiation, not by gemstones. You might be able to get a marginal focal point, but you would almost have no intensity over distance
 
There a many different types of lasers, most of which do not need any kind of gemstone to function.Laser pointers use a semiconductor laser diode.































[url="Types of LasersThere are many different types of lasers. The laser medium can be a solid, gas, liquid or semiconductor. Lasers are commonly designated by the type of lasing material employed: Solid-state lasers have lasing material distributed in a solid matrix (such as the ruby or neodymium:yttrium-aluminum garnet "Yag" lasers). The neodymium-Yag laser emits infrared light at 1,064 nanometers (nm). A nanometer is 1x10-9 meters. Gas lasers (helium and helium-neon, HeNe, are the most common gas lasers) have a primary output of visible red light. CO2 lasers emit energy in the far-infrared, and are used for cutting hard materials. Excimer lasers (the name is derived from the terms excited and dimers) use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon. When electrically stimulated, a pseudo molecule (dimer) is produced. When lased, the dimer produces light in the ultraviolet range. Dye lasers use complex organic dyes, such as rhodamine 6G, in liquid solution or suspension as lasing media. They are tunable over a broad range of wavelengths. Semiconductor lasers, sometimes called diode lasers, are not solid-state lasers. These electronic devices are generally very small and use low power. They may be built into larger arrays, such as the writing source in some laser printers or CD players."from "How Stuff Works" at http://science.howstuffworks.com/laser7.htmWikihttp://en.wikipedia.org/wiki/List_of_laser_types]"Types of LasersThere are many d[/url]
