Описание: Properties of laser beams | Monochromaticity , coherence, directionality etc. | Engineering Physics

This topic explains the fundamental properties of laser beams, which distinguish lasers from ordinary light sources and form an important part of Engineering Physics syllabus for B.Tech 1st year students.

The lecture covers monochromaticity, explaining how laser light consists of a very narrow range of wavelengths. Coherence is discussed in detail, including temporal coherence and spatial coherence, with simple explanations and examples. The property of high directionality (low divergence) is explained by describing how laser beams travel long distances with minimal spreading.

Other important properties such as high intensity (brightness) and polarization are also included. These concepts are presented in a clear, exam-oriented manner, making the topic useful for RGPV and other university exams, viva, and conceptual understanding.
