Generation of high-energy secondary pulsed molecular beams

A method is suggested for generating high-intensity secondary pulsed molecu lar beams in which the kinetic energy of molecules can be controlled by an intense laser IR radiation through the vibrational excitation of molecules in the source. High-intensity [greater than or equal to 10(20) molecule/(sr s)] SF6 molecular beams with a kinetic energy of congruent to1.0 eV withou t carrier gas and of congruent to1.9 and congruent to2.4 eV with carrier He (SF6/He = 1/10) and H-2 (SF6/H-2 = 1/10) gases, respectively, were obtaine d.
