2. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Flashlamp, laser diode Used in extremely high-power (terawatt scale), high-energy multiple beam systems for inertial confinement fusion. Nd:Glass lasers are usually frequency tripled to the third harmonic at 351 nm in laser fusion devices. Titanium sapphire (Ti:sapphire) laser 650-1100 nm Other laser Spectroscopy, LIDAR, research.

3. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   A laser can remove material very efficiently because the laser beam can be designed to deliver energy to the surface in a manner which converts a high percentage of the light energy into heat. The beam is highly focused and collimated —in most non-reflective materials like wood , plastics and enamel surfaces, the conversion of light energy to ...

4. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   Industrial laser cutting of steel with cutting instructions programmed through the CNC interface. The laser beam is generally focused using a high-quality lens on the work zone. The quality of the beam has a direct impact on the focused spot size. The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 mm) in diameter.

5. Diode-pumped solid-state laser - Wikipedia

   en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

   DPSSLs generally have a higher beam quality and can reach very high powers while maintaining a relatively good beam quality. Because the crystal pumped by the diode acts as its own laser, the quality of the output beam is independent of that of the input beam.

   These devices can generate high power outputs with good beam quality, wavelength-tunable narrow-linewidth radiation, or ultrashort laser pulses. In 2012, Nichia and OSRAM developed and manufactured commercial high-power green laser diodes (515/520 nm), which compete with traditional diode-pumped solid-state lasers.

7. LED lamp - Wikipedia

   A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
