The machines for laser engraving and laser marking are the same, so the two terms are sometimes confused by those without relevant expertise. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. [2]
A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
The United States National Research Council released a report in 2008 that endorsed the investigation of microstamping as an alternative to ballistic markings.It had concluded that a national database of ballistic markings is unworkable and that there is not enough scientific evidence that, "every gun leaves microscopic marks on bullets and cartridge cases that are unique to that weapon and ...
Laser bonding is a marking technique that uses lasers to bond an additive marking substance to a substrate.. First invented in the mid 1990s by Essilor International, this patented method [1] produces permanent marks on metal, glass, ceramic and plastic parts for a diverse range of industrial and artistic applications, ranging from aerospace and medical to the awards and engraving industries.
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") [13] [14] is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun , which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7 mm ...
A laser microjet is a water-jet-guided laser in which a pulsed laser beam is coupled into a low-pressure water jet. This is used to perform laser cutting functions while using the water jet to guide the laser beam, much like an optical fiber, through total internal reflection.
