Lasers are based on the phenomeon that when you give an atom specific energy, and some photon with some specific energy hits it, the atom will release a photon with the same wavelength and in synchrony as the one who hit him, plus the 1st photon, unchanged.
More scientifically speaking:
Lasers are composed of:
1) emission medium, which is the material whose atoms will get excited and release photons;
2) optical cavity, that will reflect the photons back and forth producing the phenomenom called stimulated emission, and let some of the rays escape (visible laser rays);
3) power source, that give energy to the atoms so their electrons become excited.

How does a laser measure work and what are its key components?
A laser measure works by emitting a laser beam to a target and measuring the time it takes for the beam to bounce back. The key components include a laser diode, a sensor, and a microprocessor to calculate the distance based on the time taken for the beam to return.
How does a laser tape measure work and what are its key components that enable accurate measurements?
A laser tape measure works by emitting a laser beam to a target and measuring the time it takes for the beam to bounce back. The key components that enable accurate measurements include the laser emitter, sensor, and microprocessor that calculates the distance based on the time taken for the laser beam to return.
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.
How does optical lever work?
An optical lever works by using a laser beam and a mirror attached to the system being measured. As the system moves, it changes the angle of reflection of the laser beam on the mirror. By measuring this change in the laser beam's position, the displacement of the system can be accurately determined.
How does a laser rangefinder work to measure distances accurately?
A laser rangefinder works by emitting a laser beam towards a target and measuring the time it takes for the beam to bounce back. By calculating the speed of light and the time it takes for the beam to return, the rangefinder can accurately determine the distance to the target.
How is a laser printer used?
It works throug laser
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.
Where is it possible to learn about laser systems?
You can learn about laser systems at Universal Laser Systems, Palomar, Laser Learning, Laser Star, E Science News, Lensar, CMS Laser, How Stuff Works and Telesis.
How does a CD-ROM work?
CD-ROM works on the principle of the LASER and it is a major application of the LASER
Was Albert Einstein the first one to invent the laser?
Einstein did not invent a laser. His works in physics laid the foundation for the developement of the laser however.
How does varicose vein laser treatment work?
Laser therapy is one means of treating varicose veins. The laser works to destroy and damage the vein. The laser closes the vein preventing it from spreading further.
Where can one find information on how laser eye surgery works?
Information about laser eye surgery can be found at All About Vision, Visualase and Eye Care America. The laser surgery and health section of How Stuff Works has several tutorials and frequently asked questions about the procedure.
What is the function of laser combs?
A laser comb is used to stimulate hair growth. It works on the function of phototherapy and uses a laser frequency concentrated on your head to increase the blood flow to your scalp.
Can i connect the Lexmark E120N Laser Printer to my wireless network?
yes you can connect the Lexmark E120N Laser Printer to your wireless network, it works great.
Can a laser printer print white?
No, a laser printer cannot print white because it works by applying toner (which is usually black) onto the paper.
How does the laser ranging device work?
A laser-rang device works by using a laser beam to find horizontal fault movements. It can also use the laser beam to travel to a reflector and then back. Thus, the device can detect any change in distance to the reflector.
What is laser eiplation used for?
Laser epilation is used for the removal of hair. Laser hair removal has been around since the mid 1990's , and is growing in popularity due to it's speed and how well it works.
