Pump (left) and Brillouin (right) temporal profiles during irradiation at I=4 GW/cm². The length of interaction is 90mm at the beginning of the sequence and it decreases continuously due to the bulk damage occurrence all along this sequence. During the sequence the vertical oscilloscope range of the BSBS is reduced step by step in order to keep the temporal profile visible on the screen (3V [0-35sec.]; 1V [35-65sec.]; 0.5V [65-70sec.]; 0.20 V [70-100sec.]); 0.025 V [100-134sec.]).
