Laserblast is a 1978 American independent science fiction film directed by Michael Rae and produced by Charles Band, widely known for producing B movies.Starring Kim Milford, Cheryl Smith and Gianni Russo, featuring Keenan Wynn and Roddy McDowall, and marking the screen debut of Eddie Deezen, the plot follows an unhappy teenage loner who discovers an alien laser cannon and goes on a murderous ...
Industrial laser projectors have been on the market since the early 2000s. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be positioned or mounted, so that the employee is led by manual or semiautomatic productional processes visually.
Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.
Schematic diagram of a typical laser, showing the three major parts. A laser is constructed from three principal parts: An energy source (usually referred to as the pump or pump source), A gain medium or laser medium, and; Two or more mirrors that form an optical resonator.
Piercing usually involves a high-power pulsed laser beam which slowly makes a hole in the material, taking around 5–15 seconds for 0.5-inch-thick (13 mm) stainless steel, for example. The parallel rays of coherent light from the laser source often fall in the range between 0.06–0.08 inches (1.5–2.0 mm) in diameter.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
A white van arrives in the vicinity of the store and points a gun toward a large LCD clock. The teens have sex, the cannon fires all around, catches fire, and melts. Then doctor Yuri Svoboda, former University of San Francisco professor, menace the municipality of the town with his laser ray if he is not given five million dollars.
Chris is disheartened and Mitch must use Chris's same argument to convince him to stay. The two create a new laser, but Kent sabotages it, causing it to explode. Though initially despondent, the incident inspires Chris to design and build a six-megawatt excimer laser, which burns a hole through the campus when it is test-fired. Hathaway ...
