Laser marked electronic part. Laser engraving is the practice of using lasers to engrave an object. The engraving process renders a design by physically cutting into the object to remove material. The technique does not involve the use of inks or tool bits that contact the engraving surface and wear out, giving it an advantage over alternative ...
The main disadvantage of laser cutting is the high power consumption. Industrial laser efficiency may range from 5% to 45%. [18] The power consumption and efficiency of any particular laser will vary depending on output power and operating parameters. This will depend on the type of laser and how well the laser is matched to the work at hand.
High-speed LMD (also known as EHLA [8]) differs from conventional LMD in the focal point of the laser, and in the speed of the cladding process. For high-speed LMD, the focal point is located above the substrate. [9] [10] As powder is sprayed through the focal point, most of the laser energy is absorbed by the powder, where it melts in-flight ...
Laser beam machining. A visual of laser beam machining. Laser beam machining (LBM) is a form of machining that uses heat directed from a laser beam. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high frequency of monochromatic light will fall on the surface, thus heating, melting and vaporizing ...
Laser. A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission ...
