For minimizing the spatial cross-sectional pulse width difference in the reflected SBS compressed beam, two new methods, blocking beam edge and parameter optimization. are proposed and compared experimentally. Results show that the sub-nanosecond compressed pulse width at the beam edge can be obtained by using both two methods in this paper. The pulse width difference between the beam center and the edge is minimized through selecting a proper medium and the optimized structural parameters in a single-cell SBS compressor. Its energy efficiency reaches up to 81.5% by using the medium HT110 and is two times higher than that of the blocking beam edge method. The compressed pulse width's stability improved greatly by using these two methods. (C) 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
