can you tell me about lasers and the project , t.h.e.l?

"The cooperative Tactical High Energy Laser (THEL) Demonstrator ACTD was initiated by a memorandum of agreement between the United States and the Government of Israel on 18 July 1996. The THEL is a high- energy laser weapon system that uses proven laser beam generation technologies, proven beam- pointing technologies, and existing sensors and communication networks to provide a new active defense capability in counterair missions. The THEL can provide an innovative solution not offered by other systems or technologies for the acquisition and close-in engagement problems associated with short- to medium-range threats, thereby significantly enhancing coverage of combat forces and theater-level assets. The THEL low-cost per kill (about $3,000 per kill) will also provide a cost-effective defense against low-cost air threats. It features up to 60 shots without reloading and a P(k) near 1 at ranges of some 5 km."

Are you asking how a laser is made, or what sort of things can be made to lase?

Dr. Ali Javan invented the first gas or Helium Neon Laser - in 1960.\n\nGas Laser\n\nA gas laser is a laser in which an electric current is discharged through a gas to produce light. The first gas laser, the Helium-neon, was invented by an Iranian physicist Ali Javan. He later received the Albert Einstein Award for his achievements.\n\nAdvantages\n\n    * High volume of active material\n    * Active material is relatively inexpensive\n    * Almost impossible to damage the active material\n    * Heat can be removed quickly from the cavity\n\nTypes of gas laser\n\n     Helium-neon laser\n     Argon laser\n     Krypton laser\n     Xenon laser\n     Nitrogen laser\n     Carbon dioxide laser\n     Ion laser

The answer is Yes. And they did it. Ok it was a laser ( I think) \n\n  There was an article on a proton accelerator or something of that nature, not sure what the experiment was but the laser hit before button was pushed. Mind you it was a nano second difference but the laser hit before button was pushed.\n\n It was on yahoo news about 2 years ago. In Tech & science area.

Use a plasma beam... God havent you seen ghostbuster.

i think that you should try to make some working models of semi conductors and and their use in the LED as you will search for the led then you will find that how semi. cond. helped to enrich the fields of leds . and i think that either you can go with the working projet of radar and how they used . or on lasers. lasers is really an interestin field. and i don't have any idea bout the chems. go to the discovery kids.com site and you will thousand of project reports.

There is a great article to read on this, from How Stuff Works.  Its under "How Lightning Works", but it talks about both lightning and thunder.  My students got a lot out of it.

If you could find a transition between an inverted state and a ground state of 1 joule, you could probably make a laser of that frequency. At this point, hard gamma rays are the limit we have done.

The blue-green is so it will penetrate the oceans.  (Water absorbs red and other colours).\n\nCommunications by lasers cannot be listened to by enemies or other parties unless they are directly in the beam's path.  Combined with encryption the laser communications are very secure.\n\nAlso the current VLF (Very Low Frequency) communication systems cannot transfer data very fast so even small messages can take many minutes to transmit.  Lasers are capable of very high data rates (just look at CDs and DVDs).

Who added the laser part?  There are no stinkin lasers.\nWe don't need no stinkin lasers.  It's not a laser. \nIts just a big blue light.

A LASER (Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons.\nThe verb "to lase" means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back-formation of the term laser.

You can try the following web sites:\n\nhttp://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/light/u12l1e.html\n\nhttp://www.uwgb.edu/dutchs/petrolgy/genlight.htm

Yes, but it would be expensive to build the equipment and incredibly dangerous - imagine if the laser was hit by a small bit of space debris and the laser light moved - it would be like dropping a fire-bomb.  \n\nFar better to harvest the natural sunlight when it reaches the earth!

poor fella! nobody's answered. there is a story, a complicated one for that matter. it ties into the bag-on-line adventures, a couple comic books written by singer claudio sanchez that are quite sci-fi in nature. umm... hit up the coheedandcambria.com links and see if you get some more in depth info. hope that helps and be prepared to be mindboggled :P

Below are some links with some cool diagrams.  I'm not sure if it's specifically what you wanted though.  The second link has some really cool information about spectral transitions in a LASER.
