2. Laser lighting display - Wikipedia

   en.wikipedia.org/wiki/Laser_lighting_display

   Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection ...

3. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).

4. Laser pointer - Wikipedia

   en.wikipedia.org/wiki/Laser_pointer

   Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. 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.

5. List of laser applications - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_applications

   Most types of laser are an inherently pure source of light; they emit near-monochromatic light with a very well defined range of wavelengths.By careful design of the laser components, the purity of the laser light (measured as the "linewidth") can be improved more than the purity of any other light source.

6. Powerlight Technologies - Wikipedia

   en.wikipedia.org/wiki/Powerlight_Technologies

   The electrical-to-optical conversion efficiency of modern laser technology can be as high as 85%, [8] and off-the-shelf semiconductor diode lasers can have an output efficiency of around 50%. [9] The optical-to-electrical conversion efficiency of a photovoltaic receiver can be over 50% for monochromatic (or laser) light. [10]

7. Light fixture - Wikipedia

   en.wikipedia.org/wiki/Light_fixture

   A light fixture (US English), light fitting (UK English), or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. [1] All light fixtures have a fixture body and one or more lamps.

8. Titanium-sapphire laser - Wikipedia

   en.wikipedia.org/wiki/Titanium-sapphire_laser

   Part of a Ti:sapphire oscillator. The Ti:sapphire crystal is the bright red light source on the left. The green light is from the pump diode. Titanium-sapphire lasers (also known as Ti:sapphire lasers, Ti:Al 2 O 3 lasers or Ti:sapphs) are tunable lasers which emit red and near-infrared light in the range from 650 to 1100 nanometers.

9. Laser - Wikipedia

   en.wikipedia.org/wiki/Laser

   Class 4 lasers (≥ 500 mW) can burn skin, and in some cases, even scattered light from these lasers can cause eye and/or skin damage. Many industrial and scientific lasers are in this class. The indicated powers are for visible-light, continuous-wave lasers. For pulsed lasers and invisible wavelengths, other power limits apply.
