EXPERIMENT OBSERVATION OF SMALL-SCALE THERMAL-BLOOMING INSTABILITY

The experimental simulation results of instability of Stimulated Thermal Rayleigh Scattering (STRS) are reported in the paper, which include the studies on the process of instability of the sinusoidal perturbation source propagating in the thermal-blooming medium and the experimental studies on the increase of the small-scale thermal-blooming instability under different perturbation frequencies and different light power, and thus proves that the small-scale instability caused by thermal-blooming increases exponentially as laser propagation in the absorbing medium.
