Paper Abstract

Though phase-conjugation fidelity of stimulated Brillouin scattering (SBS) has been widely investigated, seldom attention is paid to pulse-shape fidelity. However, some applications of SBS phase conjugate mirror (PCM) require nearly identical SBS pulse shapes with pump pulses, i.e. high pulse-shape fidelity. To avoid the pulse compression effect in common SBS PCM, a novel scheme with a Stokes seed injection into the SBS generator is suggested and investigated experimentally. Experimentally results show that SBS duration becomes wider with increasing of the seed intensity, but shorter focal length can get wider duration. Pulse-shape fidelities at points of the widest duration are calculated as about 92% and 73% with focal lengths 5cm and 10cm respectively. Compared with 40% and 48% of cases without the Stokes seed, it is showed that seed injection improves the shape fidelity.
