Laser Equipment FAQ

What colors can lasers be?

The color is dependent on the frequency of the light stream, but the colors can come in all the variety of colors you can think of presently. The laser is simply a focused beam of radiated light, which makes the laser ideal of lightshows. The majority of governmental bodies have restrictions on the usage of lasers because of the potential for eye damage, even in low intensity lasers. For that reasons, at concerts, clubs, and other venues some states, such as New York, require laser stops, which prevent the lasers from dipping down into the crowd, or up onto the stadium seating. The pervasive use of lasers really began in the 1970s with bands such as The Who and Blue Oyster Cult which released a CD showing the band members on laser beams. The use is still done with lasers capable of putting images up on a wall of simply up in the air with plane lasers and conical shapes forming laser tunnels. Typically, there are also measurements for the continuous movement of the lasers so that there is limited exposure per individual, also resulting in a drastically reduced potential for injury to the average consumer.

Have lasers been weaponized?

Yes, the United States Air Force currently has an established set of adapted Boeing 747s which have large MW class lasers on the front which are used to destroy ballistic missiles in the initial stages of their deployment. The total cost of this endeavor was quite sizable and multiple organizations played a role in creating a large mobile turret that is affixed to the front of the Boeing 747. The lasers and planes are used in coordination with the rest of the North American Aerospace Defense Command to target large heat signatures that can indicate a missile launch. Track them with the same satellites and then destroy the missile in the launch phase with the lasers on the front of these jets. The dilemma with these jets is that they must be within a few hundred kilometers of the missile and target it in the initial stages of launch, otherwise the atmosphere will interfere with the strength of the laser. Lastly, this whole process of targeting, tracking, and destruction takes 8-12 seconds.

What is the highest power laser in use today?

At the National Ignition Facility in Livermore, California, there is a 700 terawatt pulse laser than can also record a measurement of 1.8 million Joules of energy. The facility uses a 192 laser chambers over 400 feet to decimate fuel within the target chamber that is 10 meters across. The chamber is currently being fitted with shielding to protect it from the fusion they hope to create within it. The idea behind a physics ignition is to create a reaction where you receive more into it than you get out of it. Fusion could work in this manner if the laboratory creates a small sun, where the reactions continually eat energy fuel in the form of heavy hydrogen atoms, but produce a ridiculous output from the measured, consistent fusion. Most importantly, the reaction has an output that is greater than its initial input. The idea is that we could harness this energy for electrical production and turn to a greener age of energy consumption. However, the laboratory in Livermore has received a failing management grade as it is years behind schedule and has cost over one billion dollars. They had an initial firing phase in 2009, and plan to start the attempted ignition reactions on fuel smaller than a pinky’s fingernail in 2010, but, as stated before, must first install shielding to protect the locals and the scientists from the radiation emission that will ensue, if it is successful.
