A scheme is presented for amplifying weak Stokes signals from water using mixture medium of CS2/CCl4 in a double-stage non-collinear Brillouin amplification system. A frequency doubled Nd:YAG laser is used to produce single-mode pulses of 5.5-ns duration. Results show that choosing mixture liquid of CS2/CCl4 as amplifier medium has advantages over pure CS2. Maximum gain can be obtained by changing...
In this paper, a method of choosing mixture medium in two-cell stimulated Brillouin scattering (SBS) system to improve the system performance is proposed. The Brillouin frequency shift (BFS) of mixture medium varies with the mixing ratio and thus the difference of the BFS between the two cells can be eliminated. The two-cell SBS system with acetone (C3H6O) in its generator cell and mixture liquid...
