Query: Coherent stacking of laser pulses in a high-Q optical cavity for
  accelerator applications   We have performed the harmonic analysis of the steady-state coherent
pulse-stacking process in a high-Q Fabry-Perot cavity. The expression for the
stacked pulse shape is obtained as a function of both the laser cavity and
pulse-stacking cavity parameters. We have also estimated the pulse power gains
attainable in the laser-optical system of NESTOR storage ring, which is under
development at Kharkov Institute of Physics and Technology. It is shown that
high power gains (~10000) can be, in principle, achieved in a cavity, formed
with low-absorption, high reflectivity (R~0.9999) mirrors, if the laser carrier
frequency will be matched to the second harmonic frequency of the
pulse-stacking cavity. This means a development of the sophisticated frequency
stabilization loop for maintaining the cavity length constant within a
sub-nanometer range.
