Phonon-retention effects on stimulated Brillouin scattering from micrometer-sized droplets illuminated with multiple short laser pulses

Cavity enhanced droplet spectroscopy: Principles, perspectives and prospects

“…The combination of these three factors permits the observation of non-linear optical processes in spherical droplets at PCCP www.rsc.org/pccp much lower incident threshold intensities than have been observed in bulk samples. These processes include lasing, 7,11 stimulated Raman scattering (SRS), 8,[12][13][14][15][16] coherent 17 and stimulated 18 anti-Stokes Raman scattering, high-order SRS, 10,19 stimulated Brillouin scattering (SBS), 10,[20][21][22] and third order sum frequency generation. 23,24 Distinctions between droplet and bulk phase non-linear optical processes are well-illustrated by SRS.…”
