Controlling of the channeling radiation by ultra-short laser pulses

Channeling radiation of moderate energy electrons in the presence of laser beams

“…If the initial phase is not fixed experimentally then one carries out averaging over it. In the work [20] it has been shown that the spectral distribution depends on the initial phase if the electron beam axis makes a certain angle with the channeling crystallographic planes. In the given case the beam angular distribution is symmetrical with respect to the channeling planes.…”

“…In [6][7][8][9] and many other works it has been considered the enhancement of ChR intensity periodically distorting the structure of the crystallographic planes with the help of external fields, say, with ultrasonic oscillations. In [10][11][12][13][14][15][16][17][18][19][20][21] it has been considered the possibility of obtaining SChR using laser beam photons which gives additional resonance transitions between E i and E k . To the best of our knowledge, no one of these predictions [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] on the SChR has not been confirmed experimentally.…”

“…In [20] it has been studied the influence of ultra-short laser beams and calculated the time dependence of populations and of ChR radiation intensity of a single electron depending on the carrier to envelope phase (CEP) of the applied laser pulse.…”

“…Since no one of the predictions on the SChR has been confirmed experimentally this work is devoted to the development of [18][19][20] in order to prepare an experiment.…”
