Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of this advanced textbook written for scientists who require further training in femtosecond science. Four years after pub- cation of the ?rst edition, femtosecond science has overcome new challenges and new application ?elds have become mature. It is necessary to take into account these new developments. Two main topics merged during this period that support important scienti?c activities: attosecond pulses are now gen- ated in the X-UV spectral domain, and coherent control of chemical events is now possible by tailoring the shape of femtosecond pulses. To update this advanced textbook, it was necessary to introduce these ?elds; two new ch- ters are in this second edition: “Coherent Control in Atoms, Molecules, and Solids”(Chap.11)and“AttosecondPulses”(Chap.12)withwell-documented references. Some changes, addenda, and new references are introduced in the ?rst edition’s ten original chapters to take into account new developments and updatethisadvancedtextbookwhichistheresultofascienti?cadventurethat started in 1991. At that time, the French Ministry of Education decided that, in view of the growing importance of ultrashort laser pulses for the national scienti?c community, a Femtosecond Centre should be created in France and devoted to the further education of scientists who use femtosecond pulses as a research tool and who are not specialists in lasers or even in optics.

Download or read book Femtosecond Laser 3D Micromachining for Microfluidic and Optofluidic Applications written by Koji Sugioka and published by Springer Science & Business Media. This book was released on 2013-09-24 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond lasers opened up new avenue in materials processing due to its unique features of ultrashort pulse width and extremely high peak intensity. One of the most important features of femtosecond laser processing is that strong absorption can be induced even by materials which are transparent to the femtosecond laser beam due to nonlinear multiphoton absorption. The multiphoton absorption allows us to perform not only surface but also three-dimensionally internal microfabrication of transparent materials such as glass. This capability makes it possible to directly fabricate three-dimensional microfluidics, micromechanics, microelectronics and microoptics embedded in the glass. Further, these microcomponents can be easily integrated in a single glass microchip by the simple procedure using the femtosecond laser. Thus, the femtosecond laser processing provides some advantages over conventional methods such as traditional semiconductor processing or soft lithography for fabrication of microfluidic, optofludic and lab-on-a-chip devices and thereby many researches on this topic are currently being carried out. This book presents a comprehensive review on the state of the art and future prospects of femtosecond laser processing for fabrication of microfluidics and optofludics including principle of femtosecond laser processing, detailed fabrication procedures of each microcomponent and practical applications to biochemical analysis.

Download or read book Femtosecond Laser Spectroscopy written by Peter Hannaford and published by Springer Science & Business Media. This book was released on 2005-12-27 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Birefringence and Bragg grating control in femtosecond laser written optical circuits written by and published by Luis Andre Fernandes. This book was released on 2012-12-31 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, femtosecond lasers are explored for the fabrication of fiber Bragg gratings (FBGs) in suspended core fibers (SCFs) as well as direct writing of integrated optical devices in bulk fused silica glass. The FBGs fabricated in suspended core fibers with different core geometries were demonstrated with femtosecond laser exposure through a Talbot interferometer. In this case, the use of a femtosecond laser system was crucial as it eliminates the need for the use of photosensitive fibers, which is the case for SCFs, while the Talbot interferometry setup provided flexibility in the definition of the grating periodicity, while simultaneously protecting the optical components used in the fabrication process from the high intensities reached during exposure in the proximity of the fibers. These Bragg gratings were employed to show simultaneous strain and temperature sensing. Using a femtosecond laser direct writing system, novel point-by-point fabrication arrangements, with detailed attention to the computer controlled laser beam modulation, were developed in order to correctly introduce modulation of the refractive index profile during the waveguide fabrication process. This technique enabled the development of phase and frequency control required for advanced Bragg grating waveguide (BGW) fabrication and arbitrary spectral shaping. Procedures were demonstrated for the fabrication of chirped and phased shifted BGWs for applications in temporal pulse shaping and spectral shaping that showed significantly improved feature resolutions for sensing applications. The BGWs were used as a practical sensitive tool to determine and study the waveguide birefringence inherent to the nonlinear absorption processes typical of femtosecond laser-material interaction. The control of form and stress birefringence was developed in order to accomplish the fabrication of integrated optical components for polarization control, like guided wave retarders and polarization beam splitters. Tuning of this waveguide birefringence was achieved by the introduction of stress inducing laser modification tracks that enabled the ability to both enhance or reduce the inherent birefringence. Characterization techniques were developed for the absolute determination of the birefringence based on BGWs spectrum splitting, together with crossed polarizer measurements, while novel data analysis procedures were demonstrated for the study of polarization dependent and polarization independent directional couplers with the introduction of a polarization splitting ratio which is wavelength and coupling length dependent. All of the improvements made in the understanding of waveguide birefringence control provided increased flexibility to simultaneously fabricate low polarization mode dispersion circuits, as well as more efficient and compact polarization dependent devices. The polarization aspects detailed here, together with the point-by-point fabrication system, may be further developed in the future towards the fabrication of more complex integrated devices that combine spectral, temporal, and polarization control, all achievable with the same femtosecond laser writing system. These flexible processing techniques will open new directions for writing additional functionalities in optical circuits with more compact three-dimensional geometries.
