Query: Lifetime of the A(v'=0) state and Franck-Condon factor of the A-X(0-0)
  transition of CaF measured by the saturation of laser-induced fluorescence   We describe a method for determining the radiative decay properties of a
molecule by studying the saturation of laser-induced fluorescence and the
associated power broadening of spectral lines. The fluorescence saturates
because the molecules decay to states that are not resonant with the laser. The
amplitudes and widths of two hyperfine components of a spectral line are
measured over a range of laser intensities and the results compared to a model
of the laser-molecule interaction. Using this method we measure the lifetime of
the A(v'=0) state of CaF to be tau=19.2 \pm 0.7 ns, and the Franck-Condon
factor for the transition to the X(v=0) state to be Z=0.987 (+0.013 || -0.019).
In addition, our analysis provides a measure of the hyperfine interval in the
lowest-lying state of A(v'=0), Delta_e=4.8 \pm 1.1 MHz.
