In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.
Laser level – control tool consisting of a laser beam projector that can be affixed to a tripod, and which projects a fixed red or green beam along the horizontal and/or vertical axis. A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or ...
Line laser with interchangeable lenses. A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer). This may be achieved by passing the beam through a cylindrical lens or a Powell lens. [1]
The first test was carried out on October 8, 2010, at slightly over 1 MJ. However, problems slowed the drive toward ignition-level laser energies in the 1.4–1.5 MJ range. [citation needed] One problem was the potential for damage from overheating due to a greater concentration of energy on optical components. [108]
A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
The pediatrician and a nurse explained that at that level, Zoe was at risk for learning disabilities, lower intelligence and behavioral disorders. Subsequent inspections by New York City’s health department found lead dust and paint residue throughout the family’s apartment.
