Light is amplified in a laser through a process called stimulated emission. This occurs when incoming photons trigger already excited atoms to emit identical, coherent photons, resulting in a cascade effect of more and more photons being emitted. This creates a highly concentrated, coherent beam of light.

How is light amplified in laser?
In a laser, light is amplified through a process called stimulated emission. This occurs when photons of light passing through a medium trigger atoms to emit more photons of the same frequency and direction in a cascading effect. This amplifies the intensity of the light beam and results in a coherent and focused laser output.
What is the working principle of a laser?
A laser works by emitting a concentrated beam of light through a process called stimulated emission, where photons are amplified and aligned to create a powerful and focused beam of light.
What type of energy is used in laser light?
Laser light uses electrical energy to excite the atoms or molecules in the laser medium, which then releases photons as light energy. This process is amplified through stimulated emission to produce the coherent and focused light beam characteristic of lasers.
How laser light is produced a laser gun?
A laser gun produces laser light using a process called stimulated emission, where light is amplified and emitted in a focused, coherent beam. This is achieved by exciting atoms or molecules in a gain medium with energy source, such as electricity or light. This energy input stimulates the emission of photons, resulting in a concentrated beam of laser light.

Why is one mirror partially transparent in lasers?
One mirror in a laser setup is partially transparent to allow some of the light to pass through and create the laser beam. This mirror helps establish the necessary conditions for the laser to operate, by allowing light to be amplified as it bounces back and forth between the mirrors in the laser cavity. The partially transparent mirror acts as an output coupler, allowing a portion of the laser light to be emitted as the coherent laser beam.
What is an amplified light beam?
An amplified light beam refers to a beam of light that has been increased in intensity, typically through the process of amplification using devices like lasers or optical amplifiers. This can result in a more powerful and focused beam of light, which is useful in various applications such as telecommunications, medical procedures, and scientific research.
Is laser a device that strengthens sound?
No, it works on electro magnetic radiation.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
How are lazers made?
Laser's are made by a series of lenses, and a powerful enough light source being passed through it. The lenses align the light particles so that they focus the light to a certain point, instead of radiating out randomly, like a light bulb.
Is a laser artificial sunlight?
No. Laser light is artificial light, but it is not sunlight.
