This picture is generally known as multiphoton ionization ( MPI ).
2.
The H 2 + ion is created on the leading edge of the laser pulse in the multiphoton ionization process.
3.
The beam is prevented from self-focusing indefinitely by nonlinear effects such as multiphoton ionization, which become important when the intensity becomes very high.
4.
"' Atmospheric pressure laser ionization "'is an atmospheric pressure ionization method for resonance-enhanced multiphoton ionization ( REMPI ) process.
5.
Notable were the demonstrations of GC / MS, laser desorption, gas pulsing, multiphoton ionization, and the development of calibration law for accurate mass measurement.
6.
TPCD has been applied in experiments using pump-probe, intensity dependent multiphoton optical rotation, resonance-enhanced multiphoton ionization, and polarization modulation single beam Z-scan.
7.
Resonance-enhanced multiphoton ionization ( REMPI ) is a technique applied to the spectroscopy of atoms and small molecules in which a tunable laser can be used to access an excited intermediate state.
8.
Resonance-enhanced multiphoton ionization ( REMPI ) is a form of MPI in which one or more of the photons accesses a bound-bound transition that is resonant in the atom or molecule being ionized.
9.
His undergraduate research included work in reaction dynamics with John Krenos and John Tully of Bell Laboratories, photoelectron spectroscopy with Joseph Berkowitz of Argonne National Laboratory, and raman and resonate multiphoton ionization ( REMPI ) spectroscopies under Professor Lionel Goodman.
10.
This process occurs within 10 ps of a ns laser pulse and is caused by non-linear processes such as multiphoton ionization which are enhanced by microscopic cracks at the surface, voids, and nodules, which increase the electric field.
