This book summarizes a five year research project, as well as subsequent results regarding high power diode laser systems and their application in materials processing. The text explores the entire chain of technology, from the semiconductor technology, through cooling mounting and assembly, beam shaping and system technology, to applications in the processing of such materials as metals and polymers. Includes theoretical models, a range of important parameters and practical tips.

torischen Gruppenelemente sind und in den en wir geometrische Bezie hungen wie Inzidenz undOrthogonalitat durch gruppentheoretische Rela tionen erklaren. Die rein gruppentheoretisch formulierten Axiome, die wir wahlen, stellen einfache geometrische Aussagen flir die Punkte und Geraden der metrischen Ebenen dar. Dementsprechend kann man beim Beweisen aus den Axiomen die Vorteile des gruppentheoretischen Kalktils ausnutzen, ohne den Leitfaden der Anschauung aus der Hand zu geben. Bemerkenswert ist, wie wenige Axiome notig sind. Die metrischen Ebenen, die mit den axiomatisch gegebenen Gruppen...
