What are the advantages of laser Pointers?

Space-time coupling has recently been used to generate light in free space with an adjustable set of speeds, directions, and orbits. For example, at the flight focus (the intensity of the crow repellant laser designator pulse moving with the extended Rayleigh length), vertical chroma and time CHI are combined to separate the spatial focus from the temporal and spectral position of the pulse. Controlled. The speed and direction of the propagation group can be adjusted arbitrarily with the total time.
However, in the previous results, the propagation of group velocity is freely controlled, but the flight focus can only propagate forward or backward in a specific direction. As expected, the new lightsaber will be part of Disney's immersive hotel for the next Star Wars: The Galaxy's Starcruiser. The hotel takes the first premise of Galaxy's Edge Park and promises to expand it into an interactive two-night Star Wars adventure in the style of Westworld. Safe laser operation is still an important problem in the class IIIa laser queue. This is harmless for a low-powered laser pointer, but pointing the laser directly at your pet's cat or dog is never the right indicator. Do not aim the green laser pointer at a moving vehicle, aircraft, or mirror. Reflected beams are extremely dangerous and can lead to accidents.
