Abstract

The shot-to-shot phase fidelity of a stimulated-Brillouin-scattering phase conjugator operated many times above threshold has been found to be very sensitive to the slope of the leading edge of the input pulse. For a pulse with a rising edge that is short relative to the acoustic lifetime of the stimulated-Brillouin-scattering medium, strong random fluctuations in the fidelity of the wave-front reversal are observed. However, by tailoring the leading edge of the pulse relative to the acoustic response time of the medium, good phase reproduction has been demonstrated for input energies of 100 times above threshold.

Comparison of the full quasi-Gaussian temporal profile with the truncated fast-rise-time temporal profile. The clipped pulse retained ∼90% of the energy of the full pulse. The pulse shapes were measured with a 500-MHz oscilloscope so that the 3-ns observed rise time is an upper bound to the actual rise time.

Experimentally measured reflectivity and fidelity versus input energy with a 90-atm N2 SBS cell. The measurements were made for (a) the full quasi-Gaussian temporal profile and (b) the fast-rise-time truncated temporal profile.

Fig. 4

Cross sections of the spatial profiles at the focus of the 200-cm lens for eight consecutive return pulses from the N2 SBS cell by using (a) the full quasi-Gaussian temporal profile and (b) the fast-rise-time temporal profile. The input energy was ∼200 mJ, which corresponds to >16 times the SBS threshold.
