Laser Equipment

The term laser equipment is thrown around a lot, but it is important to understand what I actually means. By definition, laser is actually an acronym for Light amplification by stimulated emission of radiation, therefore a laser is any device which emits electromagnetic radiation. The degrees are measured in watts, Joules/cm2 and other different measures of intensity, all of which is supposed to classify the purity and potency of the beam of light. The laser equipment that create the actual beams have to serve a variety of purposes. The cooling process is critical because ht high heat that comes from the high energy beams. The necessary cooling is usually measured in Kelvin’s, and is far below zero degrees Fahrenheit or Celsius.

Generally speaking, the laser is a series of amplifiers for an already powerful beam of light. Depending on the situation there might be pulse laser equipment, or continuous laser equipment that creates a constant beam with a large amount of fuel required. The fuels are dependent on the type of laser being used. The Air Force’s aerial laser turret uses a solid fuel mixture to fire a megawatt class laser in short pulses for 3-5 seconds and has enough for 30-50 shots aboard one adapted 747. For your everyday classroom laser, you might only need a battery. However, the gamut does exist and different more industrial robot welders will need a more substantial supply that the laboratory neon gas laser. All the noble gases can serve as a conduit for the chemical laser, but it will be the gases that let you know that radiation is being emitted, and not simply the light itself. The light might be at the ultraviolet range or beyond the regular range of human site.

The majority of the laser equipment falls into the categories mentioned above, amplification, cooling, and targeting. The laser equipment amplification phase does two things. It focuses the beam of light, and it removes unnecessary frequencies that might be natural harmonics of the pure source that released the beam. All of this is to purify the potency of the beam and enable it to have a stronger electrical pulse or stream at the target end of the beam. However, there is also a great deal of research and innovation into what different forms of equipment can be used to make lasers. The cooling is a critical part of the laser process, because the parts, especially in cutting edge lasers, can become warped with continuous use. The heat generated from such high electromagnetic bursts can seriously damage the equipment and may, at times, require renewed and redoubled efforts to recalibrate the machinery to accurately function. Even preliminary testing of the laser utilized liquid nitrogen to cool the laser down to 77 degrees Kelvin, which is well below zero in both the Celsius and Fahrenheit scales. In terms of Celsius, its almost 200 degrees below zero, and in terms of the Fahrenheit scale its 321 degrees below zero. Either way, the molecules are moving extremely slowly in comparison to regular room temperature movement. Lastly, you have to consider targeting. Now, not everyone is using a million-Joule laser, so precise targeting isn’t always of paramount importance. Consider the colloquial laser pen. You use it to highlight things without burning anything. If scientists at the National Ignition Facility took this approach they wouldn’t hit much of anything while simultaneously damaging their billion plus dollar laboratory. For this reason, depending on the scale of the laser in use, and the desired effect (fusion), you will need to calibrate and target the laser on a scale that is roughly linear with its potency.
