A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a ...
Low to medium power laser diodes are used in laser pointers, laser printers and CD/DVD players. Laser diodes are also frequently used to optically pump other lasers with high efficiency. The highest-power industrial laser diodes, with power of up to 20 kW, are used in industry for cutting and welding.
The Peresvet ( Russian: Пересвет ), named after Alexander Peresvet, is a Russian laser weapon for air defense and anti-satellite warfare. [4] [3] [5] The Peresvet is one of the six new Russian strategic weapons unveiled by Russian President Vladimir Putin on 1 March 2018. As of May 2022, five units of the system are claimed to be in ...
Laser Mégajoule. Coordinates: 0°47′15.91″W. Laser Mégajoule ( LMJ) is a large laser -based inertial confinement fusion (ICF) research device near Bordeaux, France, built by the French nuclear science directorate, Commissariat à l'Énergie Atomique (CEA). Laser Mégajoule plans to deliver over 1 MJ of laser energy to its targets ...
The generation lasers are short pulse (from tens of nanoseconds to femtoseconds) and high peak power lasers. Common lasers used for ultrasound generation are solid state Q-Switched Nd:YAG and gas lasers (CO 2 or Excimers). The physical principle is of thermal expansion (also called thermoelastic regime) or ablation. In the thermoelastic regime ...
Because of the high power levels available (combined with reasonable cost for the laser), CO 2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. In selective laser sintering, CO 2 lasers are used to fuse particles of plastic powder into parts.
