Figure 7
Anti-Stokes intensity of a homogeneous sample of cylindrical shape as a function of the emission angle versus the sample length L.
As the axial size of the sample increases, the emission strength of the phase-matched contribution grows (highlighted by a green box), while the amount of non-phase-matched emission reduces (outlined by a blue box). For the calculation key parameters were set to: θp;min = 13°, θp;max = 16° and θS = 4°.
