Laser Physics
Laser Physics is the branch of physics that deals with the study of lasers, which are devices that emit light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. This field encompasses the study of the principles behind laser operation, the properties of laser light, the interactions of laser light with matter, and the applications of lasers in various scientific, industrial, and medical fields. Laser Physics involves the understanding of the underlying physics of how lasers work, including the mechanisms of population inversion, optical pumping, and cavity resonance. Researchers in this field explore topics such as laser spectroscopy, laser cooling and trapping, ultrafast laser dynamics, and laser material processing.
