Figure 4: Threshold behaviour of the spatial distribution.

From: Bright emission from a random Raman laser

Figure 4

Spatial beam profiles, (a) below threshold experiment, (b) above threshold experiment, (c) below threshold simulation and (d) above threshold simulation illustrating the significant change in the spatial profile of the Raman signal above and below the threshold. Background subtraction was preformed for the experimental images.
