High-order harmonic generation

Heterodyne Interferometry Using High-Order Harmonic Generation in Mixed Gases... 

The DPM was revealed to be a very robust device and is now routinely used for most of the experiments carried out on the UHI 10 TW laser chain involving ion acceleration as well as high order harmonics generation from solid targets [62],...

If in (4.8a) the first ionization potential E01 is neglected, the electron starts its orbit in the continuum with an initial velocity viiJ) = k + A(t ) = 0 and t, t, and k are all real inside the classically allowed region. The classical boundary then is characterized by the fact that the two solutions of the afore-mentioned pair merge. (There are no such real solutions outside the classically allowed region.) This can be exploited to obtain (approximate) closed formulas for the cutoffs (corresponding to the well known cutoff E + 3.177, for high-order harmonic generation) see [31].

Other interesting related phenomena, worthy of a quantum chemist s attention, are the study of the hyperpolarizabilities of molecules trapped in a cage, e.g. a zeolite [98] or on a surface [99-102], and the whole relevance of these properties to surface property calculations, where, at the local level, there are enormous electric fields. There is also the area of very high-order harmonic generation, such as can occur in very intense laser beams and where conventional perturbation theory breaks down [103]. Finally, there is magnetic non-linear optics and here the surface, computationally, has, so to speak, only been scratched. 

Even shorter wavelengths can be reached by high-order harmonic generation in gases (See, e. g. [24,25]). 

HIGH-ORDER HARMONIC GENERATION BY CARBON NANOTUBES DENSITY MATRIX APPROACH... 

A rigorous quantum-mechanical description of the interaction of intense femtosecond laser pulses with single-wall carbon nanotubes has been presented. Quantum kinetic equations for the density matrix have been derived and solved numerically in the time domain. The influence of interband transitions on the high-order harmonics generation has been investigated.
