William Osman (born June 8, 1991) is an American YouTuber and engineer based in Ventura, California.He makes videos about science and robots. He has gone viral for a 2017 video featuring a laser cut sculpture of Vin Diesel made of a ham and cheese sandwich and a 2021 video featuring a homemade X-ray machine.
Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF 3) Used in research for laser weaponry, operated in continuous-wave mode, can have power in the megawatt range. Deuterium fluoride laser ~3800 nm (3.6 to 4.2 μm) (~90% atm. transmittance) chemical reaction US military laser prototypes. COIL (chemical oxygen–iodine laser)
A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, [1] leaving an edge with a high-quality surface finish. [2]
A plane-mounted 5-megawatt laser can be used to cook popcorn, and enough popcorn can expand to the point where it can break open a house. This myth was based on the final scene from the film Real Genius. Busted Since a 5-megawatt laser does not currently exist, the Build Team used a 10-watt laser and still successfully popped a kernel. Even ...
The carbon-dioxide laser (CO 2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available.
Helium–neon laser at the University of Chemnitz, Germany. A helium–neon laser or He–Ne laser is a type of gas laser whose high energetic gain medium consists of a mixture of helium and neon (ratio between 5:1 and 20:1) at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge.
Meanwhile, a lower power HF laser was used for the THEL (Tactical High Energy Laser) built in the late 1990s for the Israeli Ministry of Defense in cooperation with the U.S. Army SMDC. It is the first fielded high energy laser to demonstrate effectiveness in fairly realistic tests against rockets and artillery.
Laserburn is a set of wargaming rules written by Bryan Ansell in 1980. Written for use with 15 mm sci-fi figures, but also playable with 25 mm figures, the Laserburn set of rules, published by Tabletop Games, is set in a universe where man has reached the stars and the highest pinnacles of technology and is well on his way back to barbarism.
