2. Optical tweezers - Wikipedia

   en.wikipedia.org/wiki/Optical_tweezers

   However a number of other beam types have been used to trap particles, including high order laser beams i.e. Hermite-Gaussian beams (TEM xy), Laguerre-Gaussian (LG) beams (TEM pl) and Bessel beams. Optical tweezers based on Laguerre-Gaussian beams have the unique capability of trapping particles that are optically reflective and absorptive.

3. 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.

4. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation. Power levels of several watts are possible. Beam quality can be extremely high- often rivaling that of an ion laser.

5. Electro-optic modulator - Wikipedia

   en.wikipedia.org/wiki/Electro-optic_modulator

   The beam splitter divides the laser light into two paths, one of which has a phase modulator as described above. The beams are then recombined. Changing the electric field on the phase modulating path will then determine whether the two beams interfere constructively or destructively at the output, and thereby control the amplitude or intensity ...

   en.wikipedia.org/wiki/Powerlight_Technologies

   PowerLight Technologies is an American engineering firm providing power transmission via lasers.Its primary products are power-over-fiber which transmits energy in the form of laser light through an optic fiber, and "laser power beaming" in which the laser energy is transmitted through free space.

8. Laser - Wikipedia

   en.wikipedia.org/wiki/Laser

   The beam of a single transverse mode (gaussian beam) laser eventually diverges at an angle that varies inversely with the beam diameter, as required by diffraction theory. Thus, the "pencil beam" directly generated by a common helium–neon laser would spread out to a size of perhaps 500 kilometers when shone on the Moon (from the distance of ...
