Book Description
This thesis offers a thorough and informative study of high-power, high-energy optical parametric chirped pulse amplifications systems, the foundation of the next generation of femtosecond laser technology. Starting from the basics of the linear processes involved and the essential design considerations, the author clearly and systematically describes the various prerequisites of the nonlinear optical systems expected to drive attosecond physics in the coming decade. In this context, he gives an overview of methods for generating the broadband and carrier-envelope-phase stable seed pulses necessary for producing controlled electric-field waveforms in the final system; provides a guide to handling the high-power, high-energy pump lasers required to boost the pulse energy to the desired operating range; describes the design of the nonlinear optical system used to perform the amplification, including modes of operation for ultra-broadband infrared-visible pulses or narrowband (yet still ultrafast) pulses tunable over multiple octaves; and finally presents a prospective high-energy field synthesizer based upon these techniques. As such, this work is essential reading for all scientists interested in utilizing the newest generation of ultrafast systems.

Book Description
Picosecond laser pulses find diverse applications for example in material processing as well as in analysis and sensing. Fluorescence lifetime spectroscopy in particular requires pulses with variable repetition rate and moderate pulse energy. While suitable pulses in the red and blue spectral range can be provided by gain-switched laser diodes, the generation of green laser pulses requires a more elaborate setup based on second harmonic generation. The starting point is a gain-switched infrared distributed-feedback laser diode. The optimization of the laser design and the operating conditions allows to generate spectrally narrow picosecond pulses with a peak power above 1 W. Different gain media are compared for further amplification of these pulses, and options for the miniaturization of the master-oscillator power-amplifier system are explored. The resulting intense infrared pulses are then used for second harmonic generation of green picoseconds pulses. Their peak power of above 5 W exceeds all previous green pulse sources with variable repetition rate. In terms of pulse energy and background suppression, the reported green pulses are thus ideally suited for fluorescence lifetime spectroscopy

Book Description
Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

Book Description
The electronics industry in Taiwan has shifted its emphasis from consumer- to information-based products. It is enjoying the bulk of the world market in computer motherboards, keyboards, scanners and PC monitors.Optoelectronics is a growing sub-group within information-based electronics. In addition to the established areas, other technologies such as optical storage, optical signal processing, optical switching and transmission are emerging. Research efforts at universities and research institutions are strongly supported by the official bodies of the government. The articles collected in this volume are contributed by the most active researchers in the area of optics and photonics in Taiwan. The subject areas covered such as Optical Materials, Devices and Systems are by no means representative of the breadth nor depth of optical research in Taiwan. Instead, they offer a snapshot of the ongoing work that will lead to success in the commercial world in future.
