“…The Raman spectra were obtained by successive scans of 1 cm-~ of the CW dye laser. The calibration of the Raman shift was provided by frequency measurements of an accurate travelling Michelson interferometer [19]. The pressures investigated in this work were in the range 150-6800bar (135-800 amagat).…”

“…The first one is a Michelson interferometer measuring the output radiation of the CW ring dye laser before amplification. The maximum accuracy of this apparatus is ∼2 MHz [14]. The second wavemeter is based on a 1 cm −1 free spectral range thermalized Fabry-Perot cavity that operates in a pulsed mode to provide a shot-per-shot relative frequency measurement of the PDL radiation with an accuracy of ∼100 MHz.…”

We present experimental results on the modification of a molecular ionization continuum through a laser-induced continuum structure. The effect is demonstrated in nitric oxide where the resonant 2 + 1 multiphoton-ionization process of the X 2 3/2 electronic ground state is modified by dressing the continuum with the electromagnetically embedded M 2 + Rydberg state. Through selection of a two-photon rovibronic transition via the D electronic state, a single rotational ground state level is excited to the continuum with one laser field. By adding an extra dressing field, a coupling is then established between this three-photon excited ground state level and one of the M state rotational levels. The modification due to the dressed continuum results in a modification of the ground state level ionization signal in one of the decay channels where an asymmetric line-shape resonance is electromagnetically induced. Limiting effects due to ac-Stark shifts are discussed.
