Resonance ionization of rubidium using sequential diode laser-driven transitions

Conference ·
OSTI ID:10148647
Diode laser excitation of rubidium atoms at the D2 line followed by [1 + 1] ionization using a pulsed dye laser was examined. Mass-resolved D2 spectra were recorded for both natural isotopes. Excitation using two sequential diode laser photons was accomplished by counterpropagating the beam from the 780 nm laser and one from a 775.8 laser; the latter excites Rb from the {sup 5}P{sub 3/2} level to the {sup 5}D{sub 5/2} level at 25704 cm{sup {minus}1}. A photon from the R6G laser then ionized the atom. Spectra resulting from scanning the second diode laser -- with the first an an off-resonance fixed frequency revealed both two-photon and sequential [1 + 1] processes.
