High order harmonic generation (HHG) produced by the interaction of an intense laser pulse and a gas medium can provide a table top scale coherent radiation source in the short wavelength range from the extreme ultraviolet to the soft x-ray region. This book presents a study based on high order harmonic generation in a semi-infinite gas cell. Two novel schemes are presented which have been used to enhance the quality of the HHG source including the conversion efficiency, the coherence, and the cut-off photon energy. This book focuses on the phase matching of the non-linear conversion process which is the main limitation to the quality of the HHG source. In the first scheme, a combination of lens and axicon is used to create a Bessel Gaussian beam instead of only a Gaussian beam and the presence of a new geometrical phase mismatch term is demonstrated. This allows us to compensate for the phase mismatch and thus to enhance the phase matching condition. In the second scheme, the phase matching is controlled by a means of an off-axis beam. When the phase mismatch is varied, mainly due to a change in the dipole phase term, the harmonic emission can be destroyed or enhanced. This technique provides the possibility to generate very high harmonic photon energies.

High-Order Harmonics Generation in Plasmas available in PDF, EPUB and Kindle. This book comprises a detailed consideration of novel approaches developed in the field of frequency conversion of laser sources in laser-induced plasmas during the last few years. The aim of the book is to support researchers and other readers in their development in the area of high-order nonlinear spectroscopy. Particularly, the advanced studies of nanoparticles and quantum dots for the formation of new sources of radiation in different short-wavelength spectral ranges show the ways to further implement the specific features of small-sized species in a relatively new field of study—laser ablation induced high-order harmonics generation spectroscopy. Researchers involved in the development of new methods of frequency conversion will benefit from finding the most recent advances in this field. Undergraduate students will discover interesting information about recent findings in plasma harmonic research. Additionally, the usefulness of the book will be demonstrated by the potential applications of the new knowledge developed during recent years for ultrafast pulse generation using the proposed schemes of plasma-light interaction. Thus, the audience may also include those researchers involved in state-of-the-art developments in attophysics. Additionally, any professionals interested in the application of the advanced techniques for material science will also benefit from updating their knowledge of new methods of material studies using high-order nonlinear spectroscopy.

Phase Matching of High Order Harmonic Generation Using Dynamic Phase Modulation Caused by a Non-collinear Modulation Pulse available in PDF, EPUB and Kindle. Phase matching high harmonic generation (HHG) uses a single, long duration non-collinear modulating pulse intersecting the driving pulse. A femtosecond driving pulse is focused into an HHG medium (such as a noble gas) to cause high-harmonic generation (HHG), for example in the X-ray region of the spectrum, via electrons separating from and recombining with gas atoms. A non-collinear pulse intersects the driving pulse within the gas, and modulates the field seen by the electrons while separated from their atoms. The modulating pulse is low power and long duration, and its frequency and amplitude is chosen to improve HHG phase matching by increasing the areas of constructive interference between the driving pulse and the HHG, relative to the areas of destructive interference.
