Описание: This textbook extends from the basics of femtosecond physics all the way to some of the latest developments in the field. In this updated edition, the chapter on laser-driven atoms is augmented by the discussion of two-electron atoms interacting with strong and short laser pulses, as well as by a review of ATI rings and low energy structures in photo-electron spectra. In the chapter on laser-driven molecules a discussion of 2D infrared spectroscopy is incorporated. Theoretical investigations of atoms and molecules interacting with pulsed lasers up to atomic field strengths on the order of 10^16 W/cm? are leading to an understanding of many challenging experimental discoveries. The presentation starts with a brief introduction to pulsed laser physics. The basis for the non-perturbative treatment of laser-matter interaction in the book is the time-dependent Schr?dinger equation. Its analytical as well as numerical solution are laid out in some detail. The light field is treated classically and different possible gauges for the field-matter interaction are discussed. Physical phenomena, ranging from paradigmatic Rabi-oscillations in two-level systems to the ionization of atoms, the generation of high-order harmonics, the ionization and dissociation of molecules, as well as the control of chemical reactions are presented and discussed on a fundamental level. In this way, the theoretical background for state of the art experiments with strong and short laser pulses is given. The new text is augmented by several additional exercises and now contains a total of forty-eight problems, whose worked-out solutions are given in the last chapter. In addition, some detailed calculations are performed in the appendices. Furthermore, each chapter ends with references to more specialized literature.

Описание: Femtosecond laser micromachining of transparent material is a powerful and versatile technology. In fact, it can be applied to several materials. It is a maskless technology that allows rapid device prototyping, has intrinsic three-dimensional capabilities and can produce both photonic and microfluidic devices. For these reasons it is ideally suited for the fabrication of complex microsystems with unprecedented functionalities. The book is mainly focused on micromachining of transparent materials which, due to the nonlinear absorption mechanism of ultrashort pulses, allows unique three-dimensional capabilities and can be exploited for the fabrication of complex microsystems with unprecedented functionalities.This book presents an overview of the state of the art of this rapidly emerging topic with contributions from leading experts in the field, ranging from principles of nonlinear material modification to fabrication techniques and applications to photonics and optofluidics.

Описание: The cornea serves as the gateway into the eye for external images. Maintenance of corneal shapes and transparency is critical for refraction. Small changes in the smoothness of the corneal surface or in the total thickness of the cornea can lead to visual distortion. Recently, however, refractive surgery for the transparent cornea has been introduced. In this procedure, the curvature of the cornea is modified either by cutting the stroma or by laser ablation of normal corneal tissue. Given the clinical efficacy of refractive surgery, it is important to understand the anatomical and physiological structure of the cornea such as corneal collagen cross-linking. Multiple commercial femtosecond lasers have been cleared for use by the US Food and Drug Administration for ophthalmic surgery, including use in creating corneal flaps in LASIK surgery. The newest application of femtosecond lasers in ophthalmology is in cataract surgery. In LASIK surgery, all surgery procedures are done in cornea. In cataract surgery, the cornea is also cut with a femtosecond laser. Over the last decade, the field of femtosecond eye surgery has expanded rapidly, supporting the advantages of combined high-ablation precision and minimized collateral tissue effects. One of the most promising applications for femtosecond laser eye surgery has been corneal surgery, namely laser in situ keratomileusis (LASIK) surgery, where the high-pressure laser plasma non-thermally dissociates the dense corneal tissue, thereby enabling lamellar cornea procedures with minimized side effects with the subsequent excimer laser shaping the corneal surface. Millions of people worldwide have been patients for LASIK surgery and have benefited from new forms of technology. LASIK surgery includes three parts: wavefront detection, femtosecond laser flap creation, and excimer laser cornea correction. Some parts of this book focus on femtosecond laser-assisted LASIK surgery, including basic research for femtosecond laser eye surgery and tissue imaging. The newest application of femtosecond lasers in ophthalmology is cataract surgery. Currently, there are a few lasers at or near the point of commercial release, including LenSx (Alcon Laboratories Inc., Fort Worth, Texas), Catalys (Abbott Medical Optics, Santa Ana, California), LensAR (LensAR Inc., Orlando, Florida), Victus (Technolas Perfect Vision and Bausch & Lomb, Rochester, New York), and Femto LDV (Ziemer Ophthalmic Systems AG, Port, Switzerland). All laser systems share a common platformwhich includes an anterior-segment imaging system, patient interface, and femtosecond laser to imageto calculate and deliver the laser pulses. Some parts of this book explain the principle of OCT-guided femtosecond laser cataract surgery. The combination of femtosecond laser surgery and OCT imaging simultaneously guides the development of next generation femtosecond surgical lasers in cataract surgery and explores femtosecond laser surgical strategies.

Описание: This thesis combines advanced femtosecond laser micro/nanofabrication technologies and frontier bionic design principles to prepare diverse biomimetic micro/nanostructures to realize their functions. By studying the formation mechanism of the micro/nanostructures, the author identifies various artificial structural colors, three-dimensional micro/nanocage arrays, and fish-scale inspired microcone arrays in different processing environments. Multiple functions such as enhanced antireflection, hydrophobicity, and underwater superoleophobicity are achieved by precisely adjusting laser-machining parameters. This novel design and method have extensive potential applications in the context of new colorizing technologies, microfluidics, microsensors, and biomedicine.
