Figure 2: Time-resolved stimulated Raman scattering spectra.
From: Laser light triggers increased Raman amplification in the regime of nonlinear Landau damping
The SRS spectra are shown on a logarithmic scale for (a) a 6-mg cc−1, 300-μm foam plasma, (b) a 2-μm-thick CH foil and (c) the combination of the two. The SRS spectrum measured with the compound target (c) where SRS in the foam is seeded by the SRS light backscattered by the foil extends further in the short wavelengths range compared with the two other spectra (a,b). A new component is observed around t=2.7 ns and λSRS=720 nm. Dot-dashed lines have been drawn on the three spectra to indicate these particular time and wavelength.
