Theoretical Investigation on 200 ps Laser Pulses Amplification Based on Stimulated Brillouin Scattering
High efficient hundred-picosecond laser pulses amplification can be realized by scheme of stimulated Brillouin scattering (SBS) energy transfer. The amplification scheme can be used in the acquisition of shock pulse in shock-ignition. By exciting acoustic field in the liquid media, the process of energy transferring from long pulse to short pulse is realized. A SBS coupled wave equation under the transient condition is used to simulate the amplification process of 200 ps pulse in theory. The results show that SBS energy transfer scheme can amplify 200 ps laser pulse to a higher power density, and the amplification process accompanies with a certain pulse width compression.
