His research activities focus on atomic, molecular, and optical physics, including novel optoelectronic devices, sub-Doppler molecular spectroscopy, optical frequency comb synthesizers, quantum cascade lasers, fiber-based optical sensors, and molecular gas sensing.
... [in] this handbook ... the story and the complexity of the variety of methods for improving optical frequency metrology unfold, in particular, the successive improvements of the performance of devices based upon lasers. ... a pleasure to read. -Contemporary Physics, 2014 This is a beautiful and monumental work ... easy to read thanks to its clear and concise style. ... a must-read for anybody working in laser research and industry, and will be particularly helpful for Ph.D. students. -Mircea Dragoman, Optics & Photonics News, January 2014 The authors have made a considerable effort to make this book useful and interesting to different kinds of readers: they provide a detailed treatment of the basic concepts of time and frequency measurements, carefully describe different kinds of lasers and some of the most advanced laser-based measurement techniques, and finally present the latest developments in the field, with a hint to the possible future trends in applications and fundamental science. Being among the many important actors in this long story, the authors of this book are privileged witnesses of the evolution of time and frequency measurements, and can provide an informed and wide vision of this developing field from many different viewpoints. -From the Foreword by Nobel Laureate Professor Theodor W. Hansch, Ludwig-Maximilians-Universitat Munchen
