Overtone pumping spectroscopy has the limitation that, because excitation starts in the ground vibrational state, only very specific states can be accessed, e.g., the (ui,0,0) progression in HOCl and only few other states in the vicinity of the (ui,0,0) states. Stimulated emission pumping (SEP) [147], on the other hand, involves a transition to an excited electronic state, whose equilibrium geometry may be quite different from the equilibrium in the ground state. Therefore, Pranck-Condon factors are comparatively large for a wide variety of vibrational states, not just the... 

If the absorption of the probe laser is monitored via one- or two-photon ionization of the upper probe transition (Fig. 5.41b), the ion signal shows a dip when the tunable pump beam burns a hole into the common lower level population Ni (ion-dip spectroscopy). This opens another way to detect stimulated emission pumping. Now three lasers are employed (Fig. 5.41b). The first laser L is kept on a transition /) k). The molecules in the excited level k) are ionized by a second laser L2. In favorable cases photons from h may also be used for ionization, thus making...
