Abstract

We measure the spectrum of coherent Brillouin scattering (CBS) in a gas as a function of time and observe for the first time additional spectral sidebands and line shape narrowing of the Brillouin peak. We find that both effects result from the interference of the density modulation induced by the moving dipole force of the pump beams with the acoustic waves induced by their fast thermalization and are predicted by a hydrodynamic-light scattering model. These line shapes differ from both spontaneous and stimulated Brillouin scattering spectra and also from previous coherent Rayleigh-Brillouin measurements.

a) Schematic diagram of the coherent Brillouin scattering process. Two pump beams cross at a full angle of 5 degrees and interfere to form a periodic density modulation (grating) via the optical dipole force. A third probe beam is Bragg scattered from the density grating to create the signal beam whose intensity is recorded as a function of frequency difference of the pump beams. b) Temporal profile of pump (light) and probe beams (dark), for a relative delay δt = 0 ns.

CBS spectra as a function of lattice velocity for four pump-probe delays of a) 50 ns, b) 70 ns, c) 90 ns and d) 110 ns. The black trace is the experimental data and the dots are the calculated values. The observed first order sidebands are noted by −s.b and +s.b.

Plots of the spectral location of the sidebands for a range of pump-probe delays. The circles represent the first sideband maxima (n = ±1) which are observed as the closest peaks either side of the Brillouin peak for each pump-probe delay of figure 2. The squares are the 2nd sidebands (n = ±2). The solid shapes are experimental points and the hollow ones are predicted from Equation (4). The triangular shapes are from the calculated spectra. The crosses are measurements of the center of the Brillouin peak which corresponds to the speed of sound in the gas. Also included is the typical uncertainty of the observed sidebands.

Plots of the CBS spectral profile for a pump-probe delay of 110 ns comparing the experimental spectrum (black line) with the simulated spectrum for the flat top pump beam profile (red circles). Also shown (red line) is the profile calculated for a slow rise time pump pulse where almost no sidebands are observed. The vertical intensity axis is shown on a logarithmic scale to indicate that all the predicted sidebands can be observed. The inset graph is a plot of the FWHM of the measured (black squares) and calculated spectra (red circles) for a range of pump-probe delays as well as for the slow rise time pump pulses (triangles). This graph shows that due to destructive interference between the dipole force grating and the acoustic wave that the line width of the Brillouin peak is approximately 40 % lower than for the slow rise time pump beam profile.
