About the Book:
The book contains a number of experiments in Optics that can be performed with ease using He-Ne-Laser. Some of the experiments are visually impressive and aid in the understanding of physical phenomena. Further the experiments can be demonstrated to a large audience. The experiments in interference, diffraction, polarisation, spatial filtering etc. fall under this group.

There are then experiments which have relevance to measurements. The experiments on diffraction, holography, speckle phenomenon, flow etc. fall in this category. These experiments will be useful to the students both in Science and Engineering. In brief the book provides various possibilities of using a He-Ne laser in the laboratory.
