เลเซอร์ - An Overview

Lasers are distinguished from other light resources by their coherence. Spatial (or transverse) coherence is usually expressed throughout the output becoming a narrow beam, which is diffraction-minimal. Laser beams might be centered to incredibly small spots, achieving a very high irradiance, or they will have a really very low divergence to concen
