Als man damit begann, die Natur des Lichts zu erforschen, dachte wohl kaumjemand daran, daß es eines Tages möglich sein würde, mit Licht zu arbeiten,d. h. mit ihm Materialien zu bearbeiten, medizinische Eingriffe durchzuführen,Entfernungen zu messen und dergleichen mehr. Und doch ist die Erfindungdes Lasers kein singuläres Ereignis, sondern baut auf den Forschungen derletzten 300 Jahre auf, die 1678 mit Huygens Deutung ...

Laser-Beam Interactions with Materials treats, from a physicist's point of view, the wide variety of processes that lasers can induce in materials. Physical phenomena ranging from optics to shock waves are discussed, as are applications in such diverse fields as semiconductor annealing, hole drilling and fusion plasma production. The approach taken emphasizes the fundamental ideas and their interrelations. The newcomer is given the necessary ...

The International Conference on Laser Physics and Quantum Optics was held in Shanghai from August 25 to August 28, 1999, to discuss many exciting new developments in laser physics and quantum optics. The international character of the conference was manifested by the fact that scientists from over 13 countries participated and lectured at the conference. There were four keynote lectures delivered by Nobel laureate Willis Lamb, Jr., Profs. H. ...

The subject of this book is the new field of squeezing in quantum fields. This general area includes all types of systems in which quantum fluctuations are reduced below those in the normal vacuum state. The book covers the main currently known techniques of generating squeezed photon fields, together with some treatment of matter field squeezing. Both theory and experiments are covered, together with applications to communications and ...

Shuji Nakamura's development of a blue semiconductor laser on the basis of GaN opens the way for a host of new applications of semiconductor lasers. The wavelengths can be tuned by controlling the composition. For the first time it is possible to produce lasers with various wavelengths, ranging from red through yellow and green to blue, in one substrate material. This fact, together with their high efficiency, makes GaN-based lasers very useful ...
