   Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...

3. Luminous efficacy - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficacy

   This is the ratio between the total luminous flux emitted by a device and the total amount of input power (electrical, etc.) it consumes. The luminous efficacy of the source is a measure of the efficiency of the device with the output adjusted to account for the spectral response curve (the luminosity function).

4. Laser ablation - Wikipedia

   en.wikipedia.org/wiki/Laser_ablation

   Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically ...

   The Heritage-class cutter, also known as the Offshore Patrol Cutter and the Maritime Security Cutter, Medium, is a cutter class of the United States Coast Guard (USCG), developed as part of the Integrated Deepwater System Program and built by Eastern Shipbuilding [4] and Austal USA. [5] Construction of the first vessel in the class began in ...

6. Luminous flux - Wikipedia

   en.wikipedia.org/wiki/Luminous_flux

   The luminous flux is a weighted sum of the power at all wavelengths in the visible band. Light outside the visible band does not contribute. The ratio of the total luminous flux to the radiant flux is called the luminous efficacy. This model of the human visual brightness perception, is standardized by the CIE and ISO. [5]
