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
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.

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.
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.
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.
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
a laser is shot out at an obbject and reflects back, this is timed by the machine then it works out the distance
The light energy is a concentrated beam of light
yes very well actually
no because it has no lasers inside of it
Gas Lasers is a kind of laser that sets free electric current over gas to carry out consistent light. Gas Lasers needs to have very high laser beams with extended coherence length.
Their relationship is the basis of virtually all modern technology from radio, television, satellites, nano-technology, lasers etc. On a more basic level the interplay between magnetic and electric fields is what makes a dynamo work, which power the lights on bicycles or converts steam power (in for example a nuclear power plant) to electricity.
I suppose that scandium was used up today in garnet lasers.
Amazon and eBay are good places to look for high power lasers. You are unlikely to find one at your local Wal-mart or Lowe's. Dragon Lasers is one example of a high powered laser you may want to research.
How do lasers work
Keith Lee is known for his work in professional wrestling as a WWE wrestler with ring name Keith Lee. He has not written any books or works outside of his wrestling career.

you can't answer this question with out knowing the power of both lasers. If you had two lasers, one yellow the other UV, BOTH WITH IDENTICAL POWER, the yellow laser would APPEAR to be more powerful since our eyes are particularly tuned to see this color. The UV laser would APPEAR to be invisible (i.e. no power) because our eyes cannot see UV light. Keep in mind that one only appears to be more powerful because of the way our eyes work, in reality they both have the same power.

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.
High powered lasers are typically used for various needs such as hair removal, surgery, spacecraft, spectrodcopy and even in investigation procedures.
High energy pulsed lasers are available for purchase on the "Newport" website. They have many models available. These lasers are quite expensive and cost thousands of dollars.
Yes, they can.
No, at least not for power reactors
