Introduction

Abstract

Laser is another important invention of mankind in the twentieth century, after the atomic energy, computer, and semiconductor. Since it was found in 1960, laser has been developed rapidly, not only giving the traditional optical science a new life but also leading to the rise of a new industry. Up to now, laser has been widely used in medicine, beauty, manufacturing industry, weapon system, and other fields, because of its characteristics of higher power, less divergence angle, better monochromaticity, shorter light pulse, and continuously tunable spectrum output compared to other light sources. Because laser technique has been developing at a rapid pace and is being applied to more and more fields, a full description of laser technique is very difficult and even impossible. Therefore, this book will focus on some recently developed and emerging laser nanofabrication techniques.
