Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.

Is light from a yellow laser safer than red or green lasers?
All lasers can be dangerous, but with a yellow laser the light doesn't remain on like most other lasers. With all lasers there is a high and low end of the spectrum.
How is laser different from other light?
Lasers have only one colour & are focused on an area while ordinary light is made of the colours you see in a rainbow and fan out.
Are mice afraid of laser lights?
No!!! Like Cats, They Are Attracted To Lasers And Other Kinds Of Lights.
what is the fastest thing in the unavirse?
Lasers or any other beam that travels at the speed of light.
What are rubies used for other than in jewelry?
They are used in LASERs (Light Amplification Stimulated Emission of Radiation)
If diamond is the hardest material how do they make it sharp for cuttin?

Which gas is used in electric bulbs?
Different kinds of light bulbs used different gasses. The incandescent bulb uses no gas - it uses a vacuum. Other kinds of bulbs may use nitrogen, argon, neon, or krypton.
A light bulb changes electrical energy to what other kinds of energy?
Heat and light
How is Atomic energy different from the other types of energy?
There are different kinds of energy that have different features
What are the other uses of krypton?
Krypton, like the other noble gases, can be used in lighting and photography. Krypton light has a large number of spectral lines, and krypton's high light output in plazmas allows it to play an important role in many high-powered gas lasers, which pick out one of the many spectral lines to amplify. There is also a specific krypton fluoride lasers.
Are there any lasers that can cut through metal?
Absolutely. There are many lasers used in industry for metal cutting. CO2 lasers are the most common, but there are many other types.
What are the different kinds of satellite?
because they are made from other people
