LASERS are physics!
Physics is the science of matter and energy.
LASERS are all about energy and in its most simplest of terms, you could easily say that laser light is a perfect example of the power of positive energy.
When a type of matter such as a gas or a crystal or a semiconductor is pumped with energy, LASERS are created. The actual laser light that we are familiar with occurs when "Population Inversion" is achieved. Population Inversion occurs when a system such as a group of atoms or molecules exists in state with more members in an excited state than in lower energy states.
Sound complicated? It is not. Think of these atoms or molecules just lying around in the lobby of a hotel. Then suddenly, a bright light, no a super bright light, brighter than any light you can imagine bursts through the hotel lobby doors and "excites" these atoms up into higher floors or excites them so much they jump through the ceiling up into higher levels of the hotel. When you have more atoms in the excited state (so excited they are up partying on the 13th floor) than in a non-excited state (still down in the lobby on the main floor) you achieve population inversion and that's when laser light can occur!
Lasers are related to physics because it takes physics to understand how lasers work!

Where is the optic chiasm?
The optic Chiasm is located where the optic nerves partially cross on the brain
What is the white matter tracts between the optic nerves and optic tracts?
Optic Chiasm
What is the optic intersection in the brain?
The optic chiasm is where the two optic nerves cross in the brain.
What is the junction of the retina and optic nerve?
The junction between the retina and the optic nerve is the optic disc.
What is the order of the neural pathway?
retina optic nerve optic chiasma optic tract lateral geniculate nucleus optic radiations primary visual cortex
Where can someone find information about Laser Optic surgery?
The best place to find information about Laser Optic Surgery is to at your eye doctor or general practitioner. They can provide detailed information about the procedure and how it will affect you.
What are the two sources of light used in Fiber Optic Cables?
laser and led
What is glaucoma laser surgery?
Glaucoma laser surgery is a medical procedure that uses laser technology to treat glaucoma, a group of eye conditions that can lead to optic nerve damage and vision loss.
Is optic neuritis related to multiple sclerosis?
There is a strong association between optic neuritis and MS
How do you use optical in a sentence?
That laser light really did damage my optic nerve.
Do Fiber-optic cable send or receive electrical signal?
No. Fibre optic cables use light instead of electrical signals. Depending on the function of the optical fibre either a laser or an LED will be used.
Why can a laser beam travel through a curled-up optical fiber?
The laser shines through the fiber optic cable because the edge of the inside of the cable can act as a mirror. This is called internal reflection.
How does information flow from North America to Europe?
Fiber optic wires along the ocean transfer the information in the form of pulses of laser.
Can a laser beam travel through a curved tube without escaping?
Depends on the characteristics of the tube. Coat the interior surface with a (perfect) mirror finish, and the laser beam will continue quite happily. Fill the tube with either multiple fiber optic strands, or build it like one huge fiber optic strand and the beam will continue as well.
What has the author Joel B Fowler written?
Joel B. Fowler has written: 'A servo controlled electro-optic modulator for cw laser power stabilization and control' -- subject(s): Modulators (Electronics), Laser beams
Who invented laser tag lasers?
Below in related links is some info on how laser tag got started.
Which products are sold on the website Laser Equipment?
The products that are sold on the website Laser Equipment are related to printers. The company sells the laser printers and recycled toner cartridges.
