2. Optical tweezers - Wikipedia

   en.wikipedia.org/wiki/Optical_tweezers

   Commonly, two traps are generated by splitting the laser beam into two orthogonally polarized beams. Optical tweezing operations with more than two traps can be realized either by time-sharing a single laser beam among several optical tweezers, [54] or by diffractively splitting the beam into

3. Laser - Wikipedia

   en.wikipedia.org/wiki/Laser

   A laser normally produces a very narrow beam of light in a single wavelength, in this case, green. Photons, the quanta of electromagnetic radiation are released and absorbed from energy levels in atoms and molecules. In a lightbulb or a star, the energy is emitted from many different levels giving photons with a broad range of energies.

4. Optical modulators using semiconductor nano-structures

   en.wikipedia.org/wiki/Optical_modulators_using...

   For highest speeds the laser beam will be focused down, forming a beam waist as it passes through the modulator. In an AOM a laser beam is caused to interact with a high frequency ultrasonic sound wave inside an optically polished block of crystal or glass (the interaction medium). By carefully orientating the laser with respect to the sound ...

5. 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.

   The Advanced Target Pointer Illuminator Aiming Laser, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...

7. 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.

9. Powerlight Technologies - Wikipedia

   en.wikipedia.org/wiki/Powerlight_Technologies

   The power beaming system uses a laser running from a power supply.To define the beam size at its destination, the laser's light can be shaped by a set of optics.This light energy can be sent through air or the vacuum of space, onto a photovoltaic (PV) receiver, where it is converted back into electricity.
