Abstract

Stimulated Brillouin scattering (SBS) from micrometer-sized single water and methanol droplets was observed with a Brillouin shift that varied within a range determined by the k-vector spread and the optical feedback provided by the droplet interface. The inability to observe SBS in carbon disulfide droplets is attributed to phase-modulation broadening of the input and Brillouin radiation resulting from the large intensity-dependent index of refraction of carbon disulfide.

The focused input beam illuminates the droplet equatorial plane at edge A or B [top view in (a) and (b)]. The Brillouin and/or elastic radiation is collected from edge W for edge-A illumination and from edge E for edge-B illumination. The dashed lines denote the specularly reflected ray on the droplet tangent face (b). The internal input rays have a k-vector spread of ΔΦ (c). Assuming that the near-backward-scattered Brillouin k-vector kSBS is tangent to the droplet, the scattering angle varies from θmin = 104° to θmax = 138° for droplets with an index of refraction n = 1.33. If both the input and Brillouin waves circumvent the droplet, then θ = 1800.

Fig. 2

Single laser shot spectra of SBS and/or elastic scattering detected by an intensified linear photodiode array placed behind a Fabry–Perot interferometer with a free spectral range (FSR) of 0.526 cm−1. The spectra shown are for three interferometric fringes from the (a) input laser, (b) a water droplet, (c) a methanol droplet, and (d) and (e) carbon disulfide droplets. The input intensity is indicated on the right. Only the Stokes SBS is observed for (b) or (c). The absence of SBS from carbon disulfide droplets in (d) and (e) is attributed to phase-modulation broadening. Spectra for (b)–(e) are for edge-B illumination and edge-E collection [see Figs. 1(b) and 1(c)].
