Abstract A century has passed after Einstein introduced us to the stimulating theory of radiation called LASER. The amazing properties of lasers make them unusual compared to the ordinary light. The properties of laser are so unique and hence have led to many exciting applications. Lasers have touched all the facets of our life through laser printers, textiles, storage devices, bar code scanners, laser surgery, LIDAR, etc. This paper is a detailed study of the laser technology and how lasers can help in sustainable development in many fields such as manufacturing, medical, space sciences, textiles etc.
