Laser cooling permits one to sluggish atoms to approximately the rate of a mosquito and to regulate their motions with unparalleled precision. This dependent approach, wherein atoms, molecules, or even microscopic beads of glass, should be trapped in small areas of unfastened area by way of beams of sunshine and in this case moved at will utilizing different beams, has revolutionized many parts of physics. particularly, it presents an invaluable examine software for the research of person atoms, for investigating the main points of chemical reactions, or even for the learn of atomic movement within the quantum area. this article starts with a evaluation of the appropriate features of quantum mechanics; it then turns to the electromagnetic interactions focused on slowing and trapping atoms, in either magnetic and optical traps. The concluding chapters talk about a vast variety of functions, together with atomic clocks, experiences of ultra-cold collision approaches, diffraction and interference of atomic beams, optical lattices, and Bose-Einstein condensation. The booklet is meant for complicated undergraduates and starting graduate scholars who've a few uncomplicated wisdom of optics and quantum mechanics. an intensive bibliography presents entry to the present learn literature.
