Volume three in this series focuses on the basic principles of light pulse compression through chirp generation and compensation inside and outside the laser cavity. Traces the developmental of light railways from before the 1896 Light Railways Act, and places the failure of the subsequent expansion in the context of financial problems of the rail industry as a whole, due most especially to the concurrent rise of motor traffic. Assesses the impact on the remote areas served, and follows the form of transportation to its terminal decline between the wars. For historians and rail buffs. Distributed by St. Martin's.
