About the Book
While retaining the basic organization of previous edition, this second edition of Lasers: Techniques and Applications has been conceived and written to reflect changes that have emerged in the understanding and teaching of the subject. A new chapter has been dedicated to the development of Optical Fibres Communication systems that followed the invention of laser in 1960, development of low optical fibres, sensitive photo detectors and efficient modulation scheme which offers certain unique advantages over rival systems wire and radio channels.
Another chapter on Fibre material manufacturing and applications has been added that discusses factors optimizing losses in the Fibre besides different fibre materials and their manufacturing methods. Also given is a brief overview of integrated optics that combines many functions into an integrated chip. In the last chapter on Laser Information Technology, use of lasers in optical data storage, laser printers, optical multiplexer are discussed.
