Superposition of Photoionization Modes
It is possible to control the spatial distribution of the dose induced by laser pulses, and the relative yields of primary photolytic species, by controlling the properties of the laser beam. The dose distribution can be conveniently shaped by inducing a superposition of the four modes of photoionization. The mixed ionization modes are: SP-OB, SP-B/OB, and F-OB.

Famous quotes containing the word modes:
“Men and women are brothers and sisters; they are not of different species; and what need be obtained to know both, but to allow for different modes of education, for situation and constitution, or perhaps I should rather say, for habits, whether good or bad.”
—Samuel Richardson (1689–1761)
