The power of a laser decreases with distance due to beam divergence, where the laser beam spreads out as it travels farther. This results in a decrease in power density at the target area. Additionally, factors such as scattering and absorption by the medium through which the laser beam travels can further attenuate the power at greater distances.
It is difficult to physically stop a laser beam, but you can block or absorb its energy using materials such as opaque objects or laser safety goggles. The effectiveness of these methods depends on the power and wavelength of the laser. Consulting with laser safety professionals is recommended to ensure proper protection.
Power broadening is an effect whereby the line-width of a laser is broadened by the laser intensity itself. Higher laser intensity leads to a larger line-width. This can be explained by considering the decay rate of atoms from the upper to lower laser level. As the laser intensity increases, this decay rate (which is linearly related to the line-width) increases due to stimulated emission.
The time it takes for a laser to damage your eye can vary, but it can happen in a fraction of a second. Factors that influence the speed of damage include the power and intensity of the laser, the wavelength of the light, and the distance between the laser and your eye.
The laser intensity formula used to calculate the power of a laser beam is Power (P) Energy (E) / Time (t).
The laser intensity equation used to calculate the power of a laser beam is P E/t, where P represents power, E represents energy, and t represents time.
2 different things. Police Radar uses the Doppler Effect to calculate a speed. Police Laser uses the Time/Distance effect. Look them up, too long to explain here.
Laser burn may effect the reading of the disc.
Distance is measured based on the Doppler effect. This has to do with a phase change in the the light based on its wavelength

A laser distance finder is capable of measuring distance with a laser. There are many brands and models with different measuring capabilities. The Bosch laser meter can read a distance from 2 inches to up to 230 feet. Many other brands have the same capabilities as well.

No. The only thing touching the disc, is a laser light, at such low power, there is no harm.
Yes, a laser measuring device uses laser technology to accurately calculate distances by measuring the time it takes for a laser pulse to bounce off a surface and return to the device. The device then uses this information to calculate the distance based on the speed of light.
One can buy a device for laser distance measurement from a variety of different retailers. One can purchase a laser distance measurement device online from websites such as Professional Equipment, EngineerSupply, and Amazon.
Laser power is a wireless transfer of heat or electricity from one location to another using laser light. Therefore this type of power is made from laser light, and one can find more detailed information about this process by visiting the Laser Motive website.
