New Edition of Understanding Lasers 

Thirty years ago, I wrote the first edition of Understanding Lasers for the old Howard W. Sams Company, which published a series of "Understanding" books on technology. I had been writing about lasers for a decade then, and wanted to share what I had learned with other people interested in laser technology. Radio Shack, which at the time was a large chain of electronics stores, put out their own edition of the book. Eventually it went out of print, and I resold the book to IEEE Press, which printed their own version of the first edition while I prepared a second edition that they published in 1994. IEEE Press asked me for a third edition in the 2000s, and by the time I finished it they had partnered with Wiley, which published it jointly in 2008. 

Now Wiley and IEEE Press have published a fourth edition, which has grown to 586 pages. Laser technology has come a long way, but the book is still an entry-level guide to what has become a rich and complex field. I make a point of spelling out acronyms, avoiding complex math, and providing essential background information on physics and optics to help readers new to the field.
