Optimally, the light should be stored for a time comparable to
the characteristic timescale of the signal. Thus if signals of
characteristic timescale 1 msec are to be searched for, the
number of bounces should be approximately 50 for an arm length of
3 km. With 50 bounces the required laser power is reduced to
W, still a formidable requirement.
