介绍了一种在单池中实现受激布里渊散射双光束共轴放大的方法,能够在单一光学池中同时实现受激布里渊散射的产生和放大.相比于传统的双池放大技术,这种方法具有结构简单、信号损失小的优点.对于激光雷达等无法采用双池放大的实际应用领域,单池放大技术更是一种必要的方法.
The amplification of the signal of stimulated Brillouin scattering (SBS) is widely used in many area. A method for amplifying the signal of SBS using dual collinear beams in a single optical cell is introduced. The stimulated Brillouin scattering can be induced and amplified in one optical cell. Comparing with previous double-cell technique, the proposed method has the advantages of simple structure and low energy loss. It is necessary for some applications with weak signal of stimulated Brillouin scattering such as lidar for remote sensing, in which double-cell technique is not suitable.
