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 ...
Xenon ion laser. Many lines throughout visible spectrum extending into the UV and IR. Electrical discharge. Scientific research. Nitrogen laser. 337.1 nm. Electrical discharge. Pumping of dye lasers, measuring air pollution, scientific research. Nitrogen lasers can operate superradiantly (without a resonator cavity).
A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue or violet. [1] Blue lasers can be produced by: direct, inorganic diode semiconductor lasers based on quantum wells of gallium (III) nitride at 380-417nm [2] [3] or indium gallium nitride at 450 ...
A “military-grade laser light” allegedly hit a Philippines coast guard vessel and temporarily blinded some of its crew members in the disputed South China Sea.
A diode-pumped solid-state laser ( DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode . DPSSLs have advantages in compactness and efficiency over other types, and high power DPSSLs have replaced ion lasers and flashlamp-pumped lasers in many scientific ...
