a beam of optic light -- basically the same light produced by the flashlight you keep in the glove compartment of your car
a beam of pure light, with waves that are all the same length
a collection of photons, which are bosons, all in the same quantum state, thus giving perfectly coherent light
a form of light energy powerful enough to be used as an instrument which can cut tissues more precisely in some situations than other techniques
a high-intensity beam of light that is used to destroy abnormal cervical or vaginal tissue
a stream of photons emitted in a narrow, coherent beam of near- monochromatic light
a very strong, hot beam of light
The cylinder of light that comes out of the laser head. This is what makes the mark on the selected material by vaporizing it.
A laser beam is a coherent beam of photons, all of the same wavelength and traveling along a tightly controlled axis.
An strong, controlled light beam powerful enough to cut, destroy, or fuse body tissues. Laser beams can be precisely focused for use in delicate operations such as eye surgery. The word stands for Light Amplification by Stimulated Emission of Radiation.
