Application To Generation of Pulsed Hard Radiation
When a laser pulse passes an electron the electron is shaken heavily, but afterwards it flies on as if nothing has happened, though a little bit of Compton scattering has taken place. Additionally an electron can either enter or leave an atom and in this process the electron can either emit an X-ray photon or absorb an X-ray photon. In a complex situation with an atom, an electron, and a laser pulse, either the energy of the X-ray photon depends on the electric field of the laser pulse at the time of creation or the energy of the electron depends on the electric field of the laser pulse at the time of leaving the atom. This is called either pulsed X-ray generation or attosecond transient recorder. Though the atom and the laser pulse interact in various ways, this is ignored here (see high harmonic generation instead).

Famous quotes containing the words application to, application, generation, hard and/or radiation:
“Preaching is the expression of the moral sentiment in application to the duties of life.”
—Ralph Waldo Emerson (1803–1882)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
“You are truly the generation in the middle! You have at once aging parents as well as maturing children to cope with, and you are not granted the deference accorded age, or the indulgence given the young.”
—Helene S. Arnstein (20th century)
“It is hard living down the tempers we are born with. We
all begin well, for in our youth there is nothing we
are more intolerant of than our own sins writ large in
others and we fight them fiercely in ourselves; but we
grow old and we see that these our sins are of all sins
the really harmless ones to own, nay that they give a
charm to any character, and so our struggle with them
dies away.”
—Gertrude Stein (1874–1946)
“There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.”
—Camille Paglia (b. 1947)
