Femtosecond lasers, which have been considered difficult to operate, expensive, and sensitive, are breaking out of laboratories and now used in various applications. This book provides a fresh perspective on femtosecond lasers discussing how the femtosecond laser is soon to become the universal light source spanning any time scale and generating any wavelength of light. Focusing on wave-like properties of the pulses and how they interact with matter and on ultrashort pulses with pulse duration shorter than 10fs, this book is written in a less technical manner, discussing the key parameters...
