This might mean that its color doesn't work in the same way. In legends, we don't know when it was created it's ancient. In canon, the Darksaber was created by Tarre Viszla before 1032 BBY. Two: The Darksaber is different from a normal lightsaber. Taylor spent about $100 for the 1,000-brick sword.Ĭheck out the full article on about the LEGO Darksaber. The colour 'Sith black' was considered a symbol of their ancient dread. “LEGO helped to fuel my Star Wars fandom,” he says. The 21 years old creative builder Taylor Walker has well over a decade of LEGO building under his belt, after a childhood spent sifting through plastic bricks to build one-of-a-kind spaceships with his twin brother, Brandon, and piecing together play sets that tied in with the prequel trilogy. published an article about a fan who created a replica of the Darksaber from… LEGO! In fact, it no longer can be considered as Legend, but… I wont spoil the plots of the episodes if you haven’t seen them yet. A laser beam is coherent light, not focused light.The last few episodes of Star Wars Rebels reignited the passion in all of us, the fans, about the legend of the Darksaber. Public Domain Image, source: Christopher S. Baird.Ī laser beam is not just focused light. Furthermore, you can't create a laser beam by cleverly focusing regular light, no matter how hard you try. You create a laser beam using stimulated emission. Stimulated emission is what causes the light in a laser beam to be coherent, and coherence is what makes a laser beam so much more useful than regular light. In fact, the word "laser" is actually an acronym that stands for "Light Amplification by Stimulated Emission of Radiation" 1. What is coherence? In the simplest picture, you can visualize a beam of light as a bundle of many little sine waves traveling through space. In this picture, coherence means that all the respective peaks of the various sine waves are lined up in space, and continue to stay lined up as the waves travel. The waves have to have approximately the same wavelength (temporal coherence) In order for the peaks to stay completely aligned everywhere, a few things have to happen:ġ.īy the phrase "lined up", we mean that if you were able to take a snapshot at a certain time of the different wave components in a light beam, you would find that all the first peaks are at the same location in space, all the second peaks are at the same distance, etc. If one wave has its consecutive peaks separated by a distance of 600 nanometers, and another wave has its peaks separated by a distance of 830 nanometers, then it should be obvious that if you line up one pair of peaks, you cannot line up any of the other pairs of peaks. Ideally, if all the wave components had exactly the same wavelength (and the other criteria listed below were met), then all the peaks could be lined up perfectly, forever. Such a situation is actually physically impossible. It would take an infinitely long beam of light in order to have all the wave components have exactly the same wavelength (the proof of this statement is not obvious and requires Fourier analysis). Despite the fact that an exactly single-wavelength beam of light is physically impossible, we can get very, very close. In fact, having a light beam that is very close to single-wavelength (called "monochromatic") is one of the main reason lasers are so useful. The waves have to be in phase (spectral coherence) Using monochromatic light can allow us to measure or trigger a very specific response in a material (e.g. The phase of a wave describes what part of a sine wave's cycle exists at a certain reference point. Two waves that are 180° out of phase will have one wave peaking at the same point in space that the other wave is bottoming out.
