Description

A laser is a device that produces light using an optical amplification technique based on the electromagnetic radiation's stimulated emission. "Light amplification by stimulated emission of radiation" is where the term "laser" first appeared. A strong foundation in the fundamental ideas controlling the field of optics is provided through laser applications. The B.E., B.Tech, and M.Tech. students will find this reference book helpful. The goal of the current book is to approach the topic of laser as an introductory course. Femtosecond Laser Spectroscopy is currently a growing field in many branches of study, including physics, chemistry, biology, and materials science, thanks to recent significant advancements in ultrafast laser technology and femtosecond nonlinear spectroscopy techniques. Additionally, efforts have been made to include the frontline areas of subjects. The advancement of laser technology and its numerous uses in communications, radiation, medicine, holography, etc. have received the attention they deserve.
