Plasma Harmonics

edited by Rashid A. Ganeev

“Higher-harmonic coherent soft X-rays can be generated by using femtosecond pulses in the short wavelength range, which is also called the water window region (4.3 ~ 2.4 nm). This technique has opened new areas of research in biology and medicine wherein biologically alive cells can be observed in femtosecond time and nanometer spatial resolution. This book presents this aspect with respect to atom and plasma physics through a new frontier that was developed by a group involving the author. I recommend this book for any researcher who will challenge a nonlinear coherent laser physics toward soft X-ray lasers and their application in any further fields.”

Plasma harmonics is a new field of laser spectroscopy.  Among the special features of plasma harmonics in laser-produced ablation plumes described in this book, the authors discuss about a wide range of nonlinear medium characteristics available by varying the conditions of laser plume production on the surface of a solid. The use of any elements of the periodic table that exist as solids largely extends the range of materials employed, together with thousands of complex solid-state samples, whereas only a few light rare gases are typically used in gas harmonics. Thus the exploration of practically any available solid-state material through the nonlinear spectroscopy comprising laser ablation and harmonic generation can be considered as a new tool for materials science.

The key step is putting, through ablation, solid molecules in gas phase at densities sufficient for plasma harmonic spectroscopy measurements. Plasma harmonics spectroscopy exploits the spectral and structural properties of various ablated solid-state materials using the propagation of short laser pulse through laser-produced plasma and generation of high-order harmonics of ultrashort laser pulses. The main goals of these studies are a search of new schemes of high-order harmonic generation using the laser ablation, generation of femtosecond and attosecond extreme ultraviolet pulses, enhancement of harmonic efficiency in these schemes, and the materials studies. The book is written by R. A. Ganeev—a leading authority in this field—and compiles and details cutting-edge research in plasma harmonics studies.
