Laser lights are spectrally pure, i.e. one wavelength, and they are coherent, i.e. all phota in phase. As a result, the beam of a laser light tends to stay as beam, and not diverge due to scattering.

What does Laser mean dealing with computers?
light
How a laser can measure the distance?
To put it simply, a laser distance measuring device consists of 2 basic parts; an (laser) emitter and a receiver. The emitter part knows when it is transmitting pulses of laser light and is synchronized with the receiver. The laser light beam is travelling at the speed of light, so the distance travelled is calculated based on the AMOUNT TIME IT TAKES TO REACH THE RECEIVER, that its round trip time divided by 2.
Why ordinary silicon diode does not emit light?
The energy band gap between the cathode and anode is too small to generate photons of higher energy than far IR.Silicon is opaque to visible light (and even IR).
What are the two sources of light used in Fiber Optic Cables?
laser and led
What weapons do you use to kill a weremecha on mechquest?
I used Palsma Pulser, Hunter's Autogun and Laser Focus and Light Cannon from my Battle Hammer v.2
What is the difference between a laser and an ordinary light in terms of colors?
An ordinary light contains more than one colour. A laser is monochromatic.
What is the difference between laser diffraction and ordinary light diffraction?
I would guess its nothing, because technically speaking a laser uses concentrated light
Difference between laser and torch light?
laser light rays don't spread and torch light ray's do
How lasers and ordinary light different?
a laser is just a focused beam of light
Why focusing of laser light is better than ordinary light?
It can simulate more.
How can you tell the difference between a laser and a beam of white light?
A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).
Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.

Difference between optical and laser mouse?
While both optical in laser mice require a light source in order to detect movement, the difference between the two technologies are optical mice use LEDs as their light source while laser mice use infrared laser that cannot be seen by the human eye. Laser mice are also much more precise than optical mice due to a higher DPI tolerance.
Difference between light emitting diode and laser?
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
What is the difference between laser and visible light In terms of wavelength wave frequency and health hazards.?
because that's the way it is....
What is the difference between continuous and pulsed wave laser?
Continuous I assume would mean a constant flow of light from the laser in the form of a wave train. Conversely, a pulse is only a single wave emitted by the laser.
