Abstract :
Four-photon interactions involving both a two-photon resonance with the 
level and a one-photon resonance with an np2P level ( 
) are investigated in detail. Gain, gain saturation, gain threshold, and forward-to-backward generation ratios are measured. Comparison with numerical estimates indicates that to 
lasing is the dominant gain mechanism but that a doubly resonant four-photon parametric oscillation makes a significant contribution. Gain saturation is dominated by population of np2P levels. Ionization is important, especially at higher pump powers.
