Answer: Laser Beams
Explanation:
The laser beam is one of the type of technology that helps in amplifying the light by using the laser principle Stimulated emission in the laser. The word "LASER" is stand for the Light amplification by stimulated emission of radiation.
The laser is one of the device that emitted the coherent light in the form of beam rays that is propagate only in one direction. The following are the laser beam technology are as follows:
- Bar code reader
- Laser surface modification
- Information processing
- Laser range
Therefore, Laser beam is the correct answer.
