Book Description
An important guide to the major techniques for generating coherent light in the mid-infrared region of the spectrum Laser-based Mid-infrared Sources and Applications gives a comprehensive overview of the existing methods for generating coherent light in the important yet difficult-to-reach mid-infrared region of the spectrum (2–20 μm) and their applications. The book describes major approaches for mid-infrared light generation including ion-doped solid-state lasers, fiber lasers, semiconductor lasers, and laser sources based on nonlinear optical frequency conversion, and reviews a range of applications: spectral recognition of molecules and trace gas sensing, biomedical and military applications, high-field physics and attoscience, and others. Every chapter starts with the fundamentals for a given technique that enables self-directed study, while extensive references help conduct deeper research. Laser-based Mid-infrared Sources and Applications provides up-to-date information on the state-of the art mid-infrared sources, discusses in detail the advancements made over the last two decades such as microresonators and interband cascade lasers, and explores novel approaches that are currently subjects of intense research such as supercontinuum and frequency combs generation. This important book: • Explains the fundamental principles and major techniques for coherent mid-infrared light generation • Discusses recent advancements and current cutting-edge research in the field • Highlights important biomedical, environmental, and military applications Written for researchers, academics, students, and engineers from different disciplines, the book helps navigate the rapidly expanding field of mid-infrared laser-based technologies.

Book Description
In the past 20 years, mid-infrared Quantum Cascade Lasers (mid-IR QCLs) have been experiencing rapid development and have become practical mid-IR sources for a variety of applications. There is particular technological interest in high efficiency lasers designed for the midwave infrared (MWIR) atmospheric window (3-5 [mu]m) and longwave infrared (LWIR) atmospheric window (8-13 [mu]m). This work presents a systematic study over mid-IR QCLs, including theoractical modeling, device fabrication and characterization. An effective bandstructure calculation method is implemented in this work for active region modeling. A standard process for fabricating mid-IR QCLs has been developed, based on which both LWIR (~ 9 [mu]m) and MWIR (~ 4 [mu]m) QCLs have been successfully demonstrated. Comprehensive testing results are analyzed and discussed, yielding valuable information about the current device design.

Book Description
Mid-infrared lasers have attracted significant attention over recent years because of the favorable scaling of many physical processes with increasing wavelength. We will present the development of mid-IR oscillators and the fabrication of gain media at UT Austin. We will then focus on two experiments using a mid-IR high average power, nanosecond laser: 1) A study of harmonic generation in polycrystalline semiconductors where we observed unusual scaling of the harmonics with the pump pulse energy. We developed a numerical model of the cascade random-quasi-phase-matched three-wave-mixing processes to explain the experimental observations. 2) A study of the plasma characteristics in laser induced breakdown spectroscopy with a nanosecond mid-IR excitation source. Using spectral measurements and a framing camera we observed a spatial separation of the plasma plume, increased emission signal with low white light generation, and a drop in the apparent plasma density with increasing pump energy. Our results can be explained by continuous heating of the plasma by the pump pulse due to the more efficient inverse bremsstrahlung absorption at longer wavelengths

Book Description
Our project was aimed at finding solutions to one of the urgent problems facing mid-infrared laser development, namely, creating high-efficiency 2.3 micrometers and 3.3 micrometers electrical laser sources operating at room temperature. These lasers are essential for chemical sensing for pollution monitoring, leak detection, chemical process control, countermeasures against heat seeking missiles, IR illumination and can be used to engage terrestrial targets from space.
