Multiphoton ionization probability
Several photons of energy below the ionization threshold may actually combine their energies to ionize an atom. This probability decreases rapidly with the number of photons required, but the development of very intense, pulsed lasers still makes it possible. In the perturbative regime (below about 10 W/cm … Vedeți mai multe Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule. Vedeți mai multe Not every interaction between a photon and an atom, or molecule, will result in photoionization. The probability of photoionization is related to the photoionization cross section of the species -- the probability of an ionization event … Vedeți mai multe • Ion source • Radiolysis Vedeți mai multe When either the laser intensity is further increased or a longer wavelength is applied as compared with the regime in which multi-photon ionization takes place, a quasi-stationary approach can be used and results in the distortion of the atomic potential in … Vedeți mai multe • Uwe Becker; David Allen Shirley (1 January 1996).
