Considering the instant when the acoustic pulse diffracts its first optical pulse, it could not be
in the crystal (1/Repetition Frequency )µs before, or it would have interfered with the previous
cycle. In the same way, it should not still be in the crystal τ
Ac
µs after without interfering with
the next cycle. This leads to loss in pulse shaping as the acoustic pulse maximum length ∆τ

(Equation 4.6) is shorter than T
