How does high power lasers work?

Answer 1

it works on the same principle as an optical mouse..

an optical mouse uses an LED to track it's movements but laser mouse uses laser

The mouse emits a laser beam and then the reflected image is received by the CMOS sensor and sent to the DSP (Digital Signal Processor) .. this cycle happens multiple times in a second .The DSP detects patterns and changes in the images and tracks the movement of the mouse and then sends the coordinates to the computer..

a typical laser mouse is 2X or 3X more sensitive than optical mice

laser mice can be used on any surface as laser reflects off anything

however, optical mice can't be used on shiny surfaces like glass

Answer 2

Usually the laser machines contains 2 parts: operation systyem and cutting part-

the theory goes like this: we make signals send out by PC or panel board, the tube which was the source beam coming can launch the beam out. After then, you can cutting the thing by the laser.

Answer 3

A laser pointer works by emitting a highly focused bright light. Since the light is so focused, it referred to as a laser. Because this light shows up as a point on whatever it falls on, it can be used to identify objects that are the subject of discussion.

Answer 4

it is a diode that emits some of its waste energy as light instead of just heating up. there is also a special lasing "cavity" around the diode junction to cause light amplification.

The first laser diodes in the late 1960s gave off about 10 watts of heat for each milliwatt of light. Modern ones give off only a few milliwatts of heat for each milliwatt of light.

Answer 5

In short, Light Amplification by Stimulated Emission of Radiation. Now, to explain. In a laser, there is something called a MEDIUM. This is where the photons are made. In all substances, there are atoms. In the atoms, there are electrons. The electrons are on orbits around the nucleus of an atom. There are more than one orbiting each atom. The electrons are EXCITED by getting hit by photons. The electrons absorb the energy from the photons they are hit by. To be on a certain orbit, the electron needs to have a certain amount of energy. When an electron is hit by a photon, it GAINS ENERGY so is jumps up to another orbit, because it has too much energy to stay on it's normal orbit. The electrons, though, ALWAYS have to go back to their original orbit (a law of physics) and in doing so, it needs to release energy in the form of a photon. Mirrors focus the light and it then comes out of the gun. There are more factors, but they are complicated and I cannot explain them for now. The main thing is the Excitation of the electrons then the release of the photons.

Answer 6

igh power laser wrks by shooting an extremely high powered beam of light through a magnification devise light is friction and heat and magnified it becomes more potent . the hardest part is finding a light bright enough to magnify and to accomplish your purpose.i simply put 24, 9 volt batteries in a solid cylender each one tied to eachother to keep the circuit going negative to posative ,positave to negative and the two leads going to the bulb than you break the glass off of the bulb and replace it with the magnification device as soon as you putt power to it you will have an example of how a small high powered laser works

Answer 7

High power lasers work by generating and amplifying a coherent beam of light using a gain medium, such as a crystal or gas. The high power is achieved through increasing the energy input and the efficiency of the laser system. The amplified light beam is then focused and directed to perform various tasks such as cutting, welding, or drilling.

Answer 8

a laser is shot out at an obbject and reflects back, this is timed by the machine then it works out the distance

Answer 9

The light energy is a concentrated beam of light
