| 摘 要： | In order to improve the performance of the two-cell stimulated Brillouin scattering （SBS） system, this paper proposes the methods of using mixtures, which require amplifier media to have small absorption rate, and generator media to have high optical breakdown threshold and Brillouin frequency shift equal to that of the amplification media. The characteristics of the two-cell SBS system are studied experimentally by using CCl4 as amplifier medium and CCl4, C2H5OH and CCl4/C2H5OH liquid mixture as generator medium pumped by Nd：YAG Q-switched laser. The obtained results show that liquid mixture in generator cell improves the power load ability, phase conjugation fidelity, energy reflectivity （ER） and ER stability.

| Abstract: | In order to improve the performance of the two-cell stimulated
Brillouin scattering (SBS) system, this paper proposes the methods
of using mixtures, which require amplifier media to have small
absorption rate, and generator media to have high optical breakdown
threshold and Brillouin frequency shift equal to that of the
amplification media. The characteristics of the two-cell SBS system
are studied experimentally by using CCl4 as amplifier medium and
CCl4, C2H5OH and CCl4/C2H5OH liquid mixture as
generator medium pumped by Nd:YAG Q-switched laser. The obtained
results show that liquid mixture in generator cell improves the power
load ability, phase conjugation fidelity, energy reflectivity (ER)
and ER stability. |
