Abstract: When excited by a powerful picosecond pulse of the second harmonic of a YAP : Nd laser, inelastic scattering lines with frequency detunings in the range of $\sim$10–130 GHz relative to the laser line were detected in suspensions of morphologically similar AltMV and PVX viruses. This scattering has a threshold nature, and the sets of its spectral lines are different for different virus samples.

Keywords: picosecond pulse, light scattering, excitation threshold, virus suspension.
