4. Laser pointer - Wikipedia

   en.wikipedia.org/wiki/Laser_pointer

   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 ...

5. Directed-energy weapon - Wikipedia

   en.wikipedia.org/wiki/Directed-energy_weapon

   The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems by means of an EMP (electromagnetic pulse).

6. Laser safety - Wikipedia

   en.wikipedia.org/wiki/Laser_safety

   Laser safety. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.

7. List of laser applications - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_applications

   Beyond this power threshold there are thermal issues related to the optics that separate these lasers from their lower-power counterparts. Laser systems in the 50-300W range are used primarily for pumping, plastic welding and soldering applications. Lasers above 300W are used in brazing, thin metal welding, and sheet metal cutting applications.

8. Laser - Wikipedia

   en.wikipedia.org/wiki/Laser

   Some lasers, particularly high-power ones, produce multimode beams, with the transverse modes often approximated using Hermite–Gaussian or Laguerre-Gaussian functions. Some high-power lasers use a flat-topped profile known as a "tophat beam". Unstable laser resonators (not used in most lasers) produce fractal-shaped beams.

9. 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 ...
