Biography
Dr. Shekhar Guha obtained his Ph.D. degree in Physics from University of
Pittsburgh and did post-doctoral work at University of Southern California.
He has been working at the Air Force Research Laboratory since 1995. His
research interests are in the field of nonlinear optical materials, especially in
the infrared.
Dr. Leonel P. Gonzalez
received his M.S. and Ph.D. degrees in Electro-Optics from the University of Dayton. He has worked in the commercial laser
industry as well as in the telecommunications field. In 2002 he returned to the
Air Force Research Laboratory and since then has been investigating nonlinear
optical materials and their applications.
"This is very unique and promises to be an extremely useful guide to a host of workers in the field. They have given a generalized presentation likely to cover most if not all situations to be encountered in the laboratory, yet also highlight several specific examples that clearly illustrate the methods. They have provided an admirable contribution to the community. If someone makes their living by designing lasers, optical parametric oscillators or other devices employing nonlinear crystals, or designing experiments incorporating laser beam propagation through linear or nonlinear media, then this book will be a welcome addition to their bookshelf."
