20-1000mW is a huge range for power and cost will vary considerably.  You should also consider your other specifications (cw/pulsed, wavelength, beam stability, beam divergence) as these will vary from laser to laser.\n\nEdmund Optics (http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productID=1341)\n20 mW green for $3.2k\n50 mW green for $5.0k\n\nThinkLasers (http://www.thinklasers.com/)\n30mw-300mW green for $595-$2250\n150mW-250mW blue for $3470-$7650

In order to get a lasing effect, you need to generate a population inversion.  Most orginary light sources (except LED's) would not be good sources of stimulated emission, but could be used to pump another material that could achieve population inversion.  This material would be called the gain medium.\n\nAlmost any transparent-ish material could possibly be made to lase (provide stimulated emission) if pumped hard enough.  I've heard of people making jello lasers and vodka lasers, for example.  These materials require a huge amount of pump (input) light and would not produce much stimulated emission.  That is why we don't use them as laser materials.  Common laser materials include CO2, Helium-Neon, Ruby, Ti:Sapphire, Nd:YAG to name a few.

The Energy Information Adminstration is a great resource for this.  Information can be organized and sorted many differnt way over many years.\nhttp://www.eia.doe.gov/\n\nhttp://tonto.eia.doe.gov/dnav/pet/hist/mg_tt_usw.htm\nIncidently, all prices are in cents.  I was confused for a minute or so until I figured that out.

Lasers are generally classified by the state of the substance excitied to make light: solid, liquid, or gas.  The fist lasers were solid (ruby), but gas lasers have become more common.\n\nLasers are also classified into pulse or continuous beam lasers.  Pulse lasers build up energy and release it periodically, usually several times a second - these have interesting industrial applications.  The lasers used in CD and DVD players and light shows are continuous beam lasers.

Gallium based semi-conductor right now is too expensive to deploy. \n\nIf you want completely out of the left field, I'd go for optical processing.

Materials that form an inverse energy distribution?  Not quite.\n\nThere are three basic components for getting a laser to work.  First, one needs an excitation source (pumping source) such as a flashlamp, an electrical spark, etc.  Second, one needs a material (the gain medium) which can exhibit what's known as population inversion - the capacity for a material to raise the electron energy level from the lower to the upper energy states.  Nearly all materials will exhibit this behavior with some more efficiently than others.  Finally, one needs to direct the stimulated energy by using a resonator.\n\nThere are many combinations of pump sources, lasing materials and optical configurations depending on the intended use.  There are solid state (ruby, Nd:YAG), gas (nitrogen, helium-neon) and semiconductor (gallium-arsenide) lasers that come in a variety of wavelengths (colors) to choose from, again, depending on what you want to do with it.\n\nJust a little bit of background: My degree is in Physics, and I've been working in the lasers and electro-optics field for the past 10+ years.  You can see what my graduate lab at SDSU looked like at: http://www.equationlab.com/mtp/quantumblog/about.html

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. \n\nGas 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. \n\nExcimer 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. \n\nDye 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. \n\nSemiconductor 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\n\nthe final result\nso with the optical frequencies of 10^14 Hz the distance travelled will be around 10,000 kms with a loss as low as 0.16db/km and a repeater at that distance

You need a green- helium safe type- laser, a converter, an adapter. \nThe company heathkit/zenith used to sell them.\n \nAnd you need a lot of money to buy the equipment.

There are a few items you will need:-\n1) A source of high voltage (to exicte the gas in your laser to emit photons). A readily availible item to do this would be the ballast (transformer) in a flourescent tube. This should get you up to between 700 to 1700 volts. It is preferabe if you have a supply closer to the upper end. This is dangerous so be sure to use appropriate precautions when working with high voltages.\n2) Choose the type of gas to excite. Gases to use include Carbon dioxide, helium, argon, neon, krypton - depending on the frequency you want from the laser. A nice big ruby could be used to make a really cool ruby laser - I could never afford to buy one though.\n3) build a laser tube - or better buy one from ebay. If you have glass blowing skills and make can make your own electrodes and embed them in the glass tube and make partial reflective mirrors on the end or the tube you can make one - but it's really tricky.\n4) fill your lser tube with the gas/gases you choose under reduced pressure.\n5) connect the electrodes to your power supply\n6) power it up....\nIt's as easy as that... uses the same basic principle to a flourescent tube, except that all the light from the partial reflector window is in phase.\n\nFor more detail I suggest you google something like "home made laser"
