Stands for Light amplification by Stimulated Emission of Radiation. A device which emits a beam of light – can be used in sensing.

A device that produce a very narrow and strong beam of light that can be used for light shows, for cutting things, or for medical operations.

Acronym for Light Amplification by Stimulated Emission of Radiation. A device that produces a coherent monochromatic beam of light which is extremely narrow and focused but still within the visible light spectrum. This is commonly used as a non-contact sensor for robots. Robotic applications include: distance finding, identifying accurate locations, surface mapping, bar code scanning, cutting, welding etc.
