Yl. Pan et al., A NEW DOPPLER-FREE OPTICAL-OPTICAL TRIPLE-RESONANCE (DF-OOTR) SPECTROSCOPY, Journal of physics. B, Atomic molecular and optical physics, 27(10), 1994, pp. 120000223-120000229
A new Doppler-free optical-optical triple-resonance (DF-OOTR) spectros
copy is reported for the first time. This high resolution technique is
simply carried out using one single mode laser like Doppler-free two-
photon spectroscopy, and can reach arbitrary levels in the high-flying
g-parity states like the optical-optical double-resonance technique i
n atomic or molecular systems. It is an effective but simple method fo
r the systematic study of atomic or molecular structures and their int
ra or internal dynamics.
