This book focuses mainly on the spectroscopy of laser materials, physics of laser materials, laser crystals and laser glasses. The spectroscopic and laser properties of rare earth and transition metal ion-doped solid state materials are systematically described based on modern quantum optics. The aim of this book is to relate the laser and spectroscopic properties to the structure and chemical composition of materials. It emphasises the nonlinear optical effects in laser materials, which are widely used in high power laser systems. The development of advanced solid state laser devices depends greatly on new laser materials. Much progress has been made recently in the development of new laser materials, and this is summarized in the book.

This book is a collection of comprehensive reviews on astrophysics at the highest energies. It puts together, for the first time, discussions of astrophysics from MeV to EeV energies and beyond. Observations at these energies reveal nuclear and particle physics throughout our galaxy as well as in the most extreme environments in the entire cosmos. These reports range from the recent spectacular results from the Compton Gamma Ray Observatory, including the latest information on enigmatic gamma ray bursts, to cosmic rays at the highest energies ever observed by man.

Worldwide research on ancient glass began in the early 20th century. A consensus has been reached in the community of Archaeology that the first manmade or synthetic glasses, based on archaeological findings, originated in the Middle East during the 5000–3000's BC. By contrast, the manufacturing technology of pottery and ceramics were well developed in ancient China. The earliest pottery and ceramics dates back to the Shang Dynasty – the Zhou Dynasty (1700 BC–770 BC), while the earliest ancient glass artifacts unearthed in China dates back to the Western Han Dynasty. Utilizing the state-of-the art analytical and spectroscopic methods, the recent findings demonstrate that China had already developed its own glassmaking technology at latest since 200 BC. There are two schools of viewpoint on the origin of ancient Chinese glass. The more common one believes that ancient Chinese glass originated from the import of glassmaking technology from the West as a result of Sino-West trade exchanges in the Western Han Dynasty (206 BC–25 AD). The other scientifically demonstrates that homemade ancient Chinese glass with unique domestic formula containing both PbO and BaO were made as early as in the Pre-Qin Period or even the Warring State Period (770 BC–221 BC), known as Youhsa or Faience.This English version of the previously published Chinese book entitled History of Ancient Chinese Glass Technology Development is for universities and research institutes where various research and educational activities of ancient glass and history are conducted. With 18 chapters, the scope of this book covers very detailed information on scientifically based findings of ancient Chinese glass development and imports and influence of foreign glass products as well as influence of the foreign glass manufacturing processes through the trade exchanges along the Silk Road(s).

This book introduces the fundamental mechanism of photonic glasses — the linear and nonlinear optical effects in glass under intense light irradiation: phot-induced absorption, refraction, polarization, frequency, coherence and monochromaticity changes. Emphasis is placed on new developments in the structure, spectroscopy and physics of new glassy materials for photonics applications, such as optical communication, optical data storage, new lasers and new photonic components and devices. The book presents the research results of the authors in new glasses for photonics over the last decade.
