“…This shortcoming is avoided by using random Raman lasers in which the width of the emission spectrum can be 1-10 cm −1 (depending on the selected media). Also, in such lasers the generation can occur at several Stokes and anti-Stokes lines (simultaneously) which are frequency shifted relatively each other by hundreds or thousands of cm −1 [7][8][9].…”

Stimulated Raman scattering (SRS) of picosecond laser radiation at 532 and 355 nm in microcrystalline powders of potassium, sodium, and strontium nitrates has been studied. One anti-Stokes and three Stokes components were generated in all samples when pumping at 532 nm. For the first time to our knowledge, random Raman lasing in the used nitrates has been obtained upon their excitation at 355 nm. In this case, the multifrequency Stokes SRS is also observed in all nitrates. We have analyzed all possible loss channels when ultraviolet radiation is used for excitation of SRS. In general, picosecond random SRS generation has been obtained at 19 spectral lines in the spectral range of 360–630 nm. In all cases, the SRS process is due to the internal symmetric mode of the (NO3)− ion with the frequency shifts of 1050 cm−1 (KNO3), 1069 cm−1 (NaNO3), and 1057 cm−1 (Sr(NO3)2).

Both backward and forward directed Stimulated Brillouin Light Scattering (SBLS) are observed in an aqueous suspension of SiO2 nanoparticles with diameters of 100 and 200 nm by using for excitation a second harmonic (λ = 532 nm, 10 ns) of a single (∼0.005 cm−1) mode YAG:Nd3+ laser. Both backward and forward directed SBLS are characterized by a low beam divergence and typically for a water Stokes shift of ≈0.25 cm−1. The microscopic explanation of forward directed SBLS in an aqueous suspension of SiO2 spherical nanoparticles is proposed.
