A physicist is a Scientist who studies or practices Physics. Physicists study a wide range of physical phenomena in many branches of physics spanning The Nobel Prize in Physics (Nobelpriset i fysik is awarded once a year by the Royal Swedish Academy of Sciences.

Kastler was born in Guebwiller, Alsace and later attended the Lycée Bartholdi in Colmar, Alsace, and Ecole Normale Supérieure in Paris in 1921.

Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Mulhouse (Mulhouse myluz Alsatian: Milhüsa or Milhüse, pronounced; Mülhausen i University of Bordeaux can refer to one or all of the four Universities in Bordeaux each of which covers a different field of study University Georges Bruhat asked him to come back to the Ecole Normale Supérieure, where he finally obtained a chair in 1952.

Collaborating with Jean Brossel, he researched quantum mechanics, the interaction between light and atoms, and spectroscopy. Quantum mechanics is the study of mechanical systems whose dimensions are close to the Atomic scale such as Molecules Atoms Electrons Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700 History See also Atomic theory, Atomism The concept that matter is composed of discrete units and cannot be divided into arbitrarily tiny Spectroscopy was originally the study of the interaction between Radiation and Matter as a function of Wavelength (λ Kastler, working on combination of optical resonance and magnetic resonance, developed the technique of "optical pumping". Optical pumping is a process in which Light is used to raise (or "pump" Electrons from a lower Energy level in an Atom or Molecule Those works led to the completion of the theory of lasers and masers. A laser is a device that emits Light ( Electromagnetic radiation) through a process called Stimulated emission. A maser is a device that produces coherent Electromagnetic waves through amplification due to Stimulated emission.

He won the Nobel Prize in Physics in 1966 "for the discovery and development of optical methods for studying Hertzian resonances in atoms". The Nobel Prize in Physics (Nobelpriset i fysik is awarded once a year by the Royal Swedish Academy of Sciences.

He was president of the board of the Institut d'optique théorique et appliquée.

Laboratoire Kastler-Brossel

Professor Kastler spent most of his research career at the Ecole Normale Supérieure in Paris where he started after the war with his student, Jean Brossel a small research group on spectroscopy.

Over the forty years that followed, this group has trained many of young physicists and had a significant impact on the development of the science of atomic physics in France. Atomic physics (or atom physics) is the field of Physics that studies atoms as an isolated system of Electrons and an atomic nucleus.

The Laboratoire de Spectroscopie hertzienne has then been renamed Laboratoire Kastler-Brossel in 1994 and has got a part of its laboratory in Université Pierre et Marie Curie and mainly at the Ecole Normale Supérieure.
