Abstract
A novel scheme using a main Brillouin amplifier in combination with a reshaping Brillouin amplifier is suggested to control the stimulated Brillouin scattering pulse shape. In this scheme, the main amplifier coarsely controls the pulse shape by changing the delay time between the pump and the Stokes seed, and the reshaping amplifier fine-tunes the pulse shape, especially the rise edge of the pulse by adjusting the distance between the two cells. Dependence of the pulse shape on the distance between the two amplifiers is experimentally researched. The results show that the encounter time and the distance between two amplifiers are the most important parameters for controlling the pulse shape. This scheme is a simple and efficient way to precisely control the pulse shape.
