Although the basic principles of lasers have remained unchanged in the past 20 years, there has been a shift in the kinds of lasers generating interest. Providing a comprehensive introduction to the operating principles and applications of lasers, this second edition of the classic book on the subject reveals the latest developments and applications of lasers. Placing more emphasis on applications of lasers and on optical physics, the book's self-contained discussions will appeal to physicists, chemists, optical scientists, engineers, and advanced undergraduate students.

London continues to fascinate a vast audience across the world, and an extensive, diverse literature now exists describing and analyzing this metropolis. The central question - what is London? - has produced many answers but none of them, the author argues, uncovers the complex ways in which knowledge is constructed in the diverse attempts to represent places and people. On the contrary: a gulf has opened up between analysis of contemporary London as a global, postcolonial city, on the one hand, and historical accounts of the imperial capital on the other. The author shows how the gap can be bridged by combining an analysis of the representation over time by various experts of London and certain localities with an investigation of the ways in which residents have represented their communities through struggles over symbolic and material resources.

Beyond the immeasurable political and economic changes it brought, colonial expansion exerted a powerful effect on Portuguese culture. And as this book demonstrates, the imperial culture that emerged over the course of four centuries was hardly a homogeneous whole, as triumphalist literature and other cultural forms mingled with recurrent doubts about the expansionist project. In a series of illuminating case studies, Ramada Curto follows the history and perception of major colonial initiatives while integrating the complex perspectives of participating agents to show how the empire’s life and culture were richly inflected by the operations of imperial expansion.
