This is the third edition of a well-known classic on ultrafast nonlinear and linear processes responsible for supercontinuum generation. Part I of the book reviews the progress achieved in experimental and theoretical understanding of the field, and goes over the applications developed since the discovery of the supercontinuum effect. The second part of the book covers recent research activity on supercontinuum phenomena and advances achieved since the publication of the previous edition. The new chapters specifically focus on: normal dispersion photonic band gap fibers; coherence in the supercontinuum; supercontinuum in the UV, NIR, and IR; and supercontinuum in XUV and X-rays for attosecond pulses. The Supercontinuum Laser Source is a definitive work by one of the discoverers of the white light effect. It is indispensable reading for any researcher or student working in the field of ultrafast laser physics.
