Recently a new, rapidly expanding field of research, X-ray quantum optics, has been formed due to the development of the coherent X-ray sources, including X-ray plasma based lasers, high harmonic generation sources and X-ray Free Electron Lasers (XFEL).

We discuss how to control the spectral/temporal characteristics of an X-ray radiation produced by these sources via variation in time/space of the parameters of its resonant interaction with a medium (atomic or nuclear transitions in gases, plasmas or solids) driven by a sufficiently strong optical or IR laser field.

Several applications of this technique are considered, including

(i) control of single X-ray photon waveform and realization of quantum interfaces between single photons and nuclear ensembles,

(ii) generation of intense attosecond pulses in the “water window” range (promising for dynamical microscopy and imaging of material and biological nano-structures, including proteins in living cells),

(iii) spectral enhancement of XFEL radiation (promising for development of long-lived quantum nuclear memory, ultrahigh resolution nuclear spectroscopy, and nuclear frequency standards).


Dr. Olga Kocharovskaya is the Distinguished Professor in the Department of Physics and Astronomy, Texas A&M University. She received her Ph.D. in Physics from N. N. Lobachevsky State University, Nizhny Novgorod, Russia and the Doctor Habilitation degree from the Institute of Applied Physics of the Russian Academy of Sciences. She joined the Texas A&M faculty in 1998 after 12 years at the Institute of Applied Physics of the Russian Academy of Sciences and 6 years of adjunct appointment as the Free Research Scientist at the Université libre de Bruxelles.

She made a number of pioneering contributions to quantum optics, quantum information science and X-ray optics. These include the predictions of the phenomena of electro-magnetically induced transparency and lasing without inversion as well as suggestion of the various schemes for coherent control of gamma-ray nuclear transitions. Her theoretical proposals were experimentally realized in many laboratories world-wide and initiated the fast growing fields of research.

A fellow of both the American Physical Society and Optical Society of America, she has received the Willis Lamb Medal for Laser Physics and Quantum Electronics, the Sigma Xi Distinguished Scientist Award and the University Distinguished Professor Award of the Texas A&M University.
