Preface

Discovered almost fifty years ago at Bell Labs (1964), the Nd:YAG laser has undergone
an enormous evolution in the years, being now widely used in both basic research and
technological applications. Nd:YAG laser is extremely versatile in its output
characteristics, yielding emission from continuous wave to very large energy pulses or
very high peak-power pulses. Also, it covers a large spectral range, namely near
infrared, visible (second harmonic) and ultraviolet (third to fifth harmonic).
This book includes new results on current research and state of the art developments
regarding Nd:YAG lasers and their applications. Nd:YAG Laser covers a wide range of
topics, from new systems (diode pumping, short pulse generation) and components (a
new semiorganic nonlinear crystal) to applications in material processing (coating,
welding, polishing, drilling, processing of metallic thin films), medicine (treatment,
drug administration) and other various fields (semiconductor nanotechnology, plasma
spectroscopy, laser induced breakdown spectroscopy).
The editor would like to thank all the chapter authors for their effort in completion of
this book.
