Figures & Tables(7)
Fig. 2. Effective pulse duration of a Gaussian waveform under different pump energies.
Fig. 3. Calculated waveform at 700 mJ with different attenuation ratios.
Fig. 4. Schematic of the experimental compressor using a generator-amplifier setup.
Fig. 5. Pulse duration evolution of output Stokes with respect to input energy using different attenuators. Three insets show compressed pulse shapes in 700 mJ with different attenuation ratios.
Fig. 6. SBS compression conversion efficiency using several attenuators. (a) Conventional conversion efficiency, which does not eliminate the tail modulation. (b) Effective energy conversion efficiency in which the energy of the tail modulation is not included in the calculations.
