Laser Doppler anemometers use a beam of light from a laser that is divided into two beams, with one propagated out of the anemometer.

Laser beam

* Laser cladding – metallic powder is blown through a movable laser beam ( e. g. mounted on a NC 5-axis machine ).

* Titan Laser: Titan is a combined nanosecond-long pulse and ultrashort-pulse ( subpicosecond ) laser, with hundreds of joules of energy in each beam.

* Laser beam profiler

* Laser beam profiler

* Laser beam profiler

Laser physicists typically choose to make θ the divergence of the beam: the far-field angle between the propagation direction and the distance from the beam axis for which the irradiance drops to 1 / e < sup > 2 </ sup > times the wavefront total irradiance.

*** Laser beam

* Laser treatment – Using a special strong beam of light of one color ( laser ) to heal a damaged area.

Red line: Laser beam.

Laser ablation, laser beam machining and wafer dicing are all industrial areas where high-speed mirror galvanometers can be found.

Laser light is scattered when a particle crosses the first beam.

A Laser Doppler velocimeter ( LDV ), also called a laser Doppler anemometer ( LDA ), focuses a laser beam into a small volume in a flowing fluid containing small particles ( naturally occurring or induced ).

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.

Laser scanners work the same way as pen type readers except that they use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the bar code.

Laser beam generators occasionally fly straight outwards from the centre of the screen.

* Laser beam welding, a type of high-precision energy beam welding

File: Laser Guide Star Sweeps Across a Starry Sky. jpg | The Earth ’ s rotation during the 30-minute exposure — and the movement of the laser as it compensated for this — is why the beam appears to fan out.

Laser levels project a beam which is visible and / or detectable by a sensor on the leveling rod.

Laser printing is a digital printing process that rapidly produces high quality text and graphics on plain paper.

Laser printers brought fast, high quality text printing with multiple fonts on a page to the business and consumer markets.

Early DVD releases held the potential to surpass their Laser Disc counterparts, but often managed only to match them for image quality — and in some cases, the Laser Disc version was preferred.

Most Laser discs were encoded with stereo ( often Dolby Surround ) CD quality audio 16bit / 44. 1 kHz tracks as well as analog audio tracks.

Another significant issue unique to Laser disc is one involving the inconsistency of playback quality between different makers and models of player.

In contrast, Laser disc playback quality is highly dependent on hardware quality.

* Laser parameters – several factors such as the laser fluence, laser energy, and ionization degree of the ablated material will affect the film quality, the stoichiometry, and the deposition flux.

Since then, the technique of Pulsed Laser Deposition has been utilized to fabricate high quality crystalline films.

Laser welding not only requires high laser power but also a high quality beam to obtain the desired " deep-weld effect ".

Laser spectroscopy is used as a tool for studying phenomena with energy in the range of visible light, for example, to study non-linear optics and forbidden transitions in media.

* Cyan Wisp is an alien-like creature from Sonic Colors with an attack move called Cyan Laser.

Laser welding is becoming more common as a method of attaching the drive plate to the disc ring with the laser typically being between 2-3KW and a feed rate 1m / minute.

General relativity also predicts the existence of gravitational waves, which have since been observed indirectly ; a direct measurement is the aim of projects such as LIGO and NASA / ESA Laser Interferometer Space Antenna and various pulsar timing arrays.

Laser science or laser physics is a branch of optics that describes the theory and practice of lasers.

Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser.

Laser microscopy is a rapidly growing field that uses laser illumination sources in various forms of microscopy.

The current laser at the UK Atomic Weapons Establishment ( AWE ), the HELEN ( High Energy Laser Embodying Neodymium ) 1-terawatt neodymium-glass laser, can access the midpoints of pressure and temperature regions and is used to acquire data for modeling on how density, temperature and pressure interact inside warheads.

The most current estimate from Lunar Laser Ranging for the acceleration is ( see Chapront et alii 2002 ): (− 25. 858 ± 0. 003 )"/ cy < sup > 2 </ sup >.

* < span style =" color :# f00 ;"> Red-Counter-air Laser </ span >-at full power, this is a powerful, horizontal double transverse wave.

The technology was also used to develop the Tactical High Energy Laser, ( THEL ) which is being tested to shoot down artillery shells.

For example, one does not buy " Laser Vision ", but the effect " Energy Blast ", and specifies that it is a laser emitted by the hero's eyes.

Rochester's Laboratory for Laser Energetics is home to the second most powerful fusion laser in the world.

** The first LAGEOS ( Laser Geodynamics Satellite ) is launched.

At CERN, this device is called the Resonance Ionization Laser Ion Source ( RILIS ).

Laser lithotripsy is another technique, which involves the use of a holmium: yttrium aluminium garnet ( Ho: YAG ) laser to fragment stones in the bladder, ureters and kidneys.

Speckle is considered to be a problem in laser based display systems like the Laser TV.

The point source has a wavelength of 633 nm ( e. g. He-Ne Laser ) and is located 1 m from the disc.

It is closely involved in major international projects such as the European X-Ray Free-Electron Laser, the Large Hadron Collider in Geneva, the IceCube Neutrino Observatory at the South Pole and the International Linear Collider.

However, this approach made a comeback following further innovations, and is being developed at both the United States National Ignition Facility, the French Laser Mégajoule as well as the planned European Union High Power laser Energy Research ( HiPER ) facility.
