ABSTRACT
In the era of advanced manufacturing, development in technology is increasing at a fast rate, but at the same time modern industries are also focusing on sustainable and economical manufacturing approaches. Laser is one such technology that has been attracting researchers and industries over decades for various manufacturing and research purposes. In the 21st century, laser has expanded its utilization in almost every field, from daily usage to aerospace applications. The efficiency of lasers helped industries to evolve rapidly and fulfil high customer demands. Laser technology opened many doors for researchers to get better insight into materials and their behaviours. It has also helped the medical sector to evolve, where patients can now go through a painless and easy mode of treatment. This chapter focuses on the application of laser technology in the academic, industrial, defence and medical sectors.
