Nonlinear optics is one of the most important fields of science and engineering, covering the generation, transmission, and control of the whole spectrum of laser pulses in solids, liquids, gases, and fibers. In turn, one of the most important ultrafast nonlinear optical processes is the supercontinuum generation - the production of intense ultrafast broadband "white light" pulses. This book is intended to fill the need of both scientists and graduate students for a single source book containing the most necessary and relevant material on supercontinuum technology. It reviews the basic principles, surveys research results, and presents the current thinking of experts in the supercontinuum field.

The Supercontinuum Laser Source

This is the third edition of a well-known classic on ultrafast nonlinear and linear processes responsible for supercontinuum generation.

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.

Mid-infrared (MIR) supercontinuum (SC) lasers are an attractive new option in the field of IR spectroscopy, especially for standoff detection. Supercontinuum radiation unites high brightness, high spatial coherence, and broadband spectral coverage, thereby surpassing thermal IR sources and challenging quantum cascade lasers. The employed SC source operates in the spectral region of 1.2–4.6 μm, filling the spectral gap where quantum cascade lasers lack broader availability. In this work, the SC radiation was recorded by compact Fabry–Pérot filter spectrometers ideally suited for sensitive standoff detection with real-time capability. The noise performance of the setup and measurements of different substances at standoff distances are presented, e.g., of different paints on a metal surface and an explosive precursor. Furthermore, the real-time capability of the setup is demonstrated by monitoring the evaporation of liquid 2-propanol.

The embryonic development of femtoscience stems from advances made in the generation of ultrashort laser pulses. Beginning with mode-locking of glass lasers in the 1960s, the development of dye lasers brought the pulse width down from picoseconds to femtoseconds. The breakthrough in solid state laser pulse generation provided the current reliable table-top laser systems capable of average power of about 1 watt, and peak power density of easily watts per square centimeter, with pulse widths in the range of four to eight femtoseconds. Pulses with peak power density reaching watts per square centimeter have been achieved in laboratory settings and, more recently, pulses of sub-femtosecond duration have been successfully generated. As concepts and methodologies have evolved over the past two decades, the realm of ultrafast science has become vast and exciting and has impacted many areas of chemistry, biology and physics, and other fields such as materials science, electrical engineering, and optical communication. In molecular science the explosive growth of this research is for fundamental reasons. In femtochemistry and femtobiology chemical bonds form and break on the femtosecond time scale, and on this scale of time we can freeze the transition states at configurations never before seen. Even for n- reactive physical changes one is observing the most elementary of molecular processes. On a time scale shorter than the vibrational and rotational periods the ensemble behaves coherently as a single-molecule trajectory.

"Defence Research & Development Canada-Valcartier (DRDC Valcartier) initiated many projects on femtosecond laser based counter-measure applications. One of the main properties of high peak power femtosecond laser pulses is their transformation into a white-light supercontinuum, which can be exploited for dazzle (and possibly damage) countermeasure purposes. Contrary to normal dazzle generated using a narrow-spectrum laser source, the white-light surpercontinuum from femtosecond laser pulses spans continuously from the ultraviolet up to the infrared. Such broadband white-light lasers are virtually impossible to block because they do not rely on a single wavelength to achieve the effect. This report presents the characterization of the white-light laser burst produced during the propagation in air of a femtosecond-Terawatt laser. The supercontinuum was generated from 200 nm in the ultraviolet up to 13.6 μm in the far infrared, which led to the first worldwide demonstration of such a broadband laser source"--Abstract, page i.
