“…The introduction of impure particles into a pure liquid medium can also significantly reduce the LIB threshold of the medium and improve the stability of the LIB [12]. LIB enhancement based on the thermal effect is a mechanism that enhances the performance of LIB through the doping of solid particles [14], where the selected doped solid particle materials are required to have a large difference in the thermal conductivity of the medium.…”

“…The existing SBS and SRS series compression technology schemes [9,10], SBS and saturated gain switch series compression technology schemes [11], and SBS and LIB series compression technology schemes have been proven to be feasible [12]. The SBS and SRS series compression technology is the earliest technological combination to realize ultrashort pulses, which has been proved in a large number of studies, and that can achieve high repetition frequency output.…”

In this paper, the laser pulse time compression technique, based on stimulated Brillouin scattering (SBS) and passive laser–induced breakdown (LIB) series technology, is investigated. By doping a SiC nanowire in a CCl4 solution of an LIB breakdown medium, the LIB generation threshold is reduced, and the stability of the LIB compression output is improved. When OD is 0.2, the output pulse width is 254.4 ps, and the corresponding energy conversion efficiency and pulse compression rate are 34.2% and 50.2%, respectively. Our experiment proves the feasibility of this scheme.

In this paper, we establish the physical model of hot damage to the stimulated Brillouin scattering (SBS) medium, and with numerical simulation method the curve of the temperature of impurity particles versus the radius is investigated. The result indicates that impurity particle has a maximal thermal effect radius and when the sizes of particles contained in the medium are near the radius, the optical breakdown phenomenon is most likely to appear, and at this point the optical breakdown threshold is lowest. We use FC-3283, GF-180 and HFE-7100 as the SBS medium in Continuum Nd: YAG laser system. The SBS medium passes through the filter with different diameters. We study the optical breakdown thresholds and energy reflectivities before and after filtration. It is demonstrated that with the filter diameter decreasing, the optical breakdown threshold increases gradually and the energy reflectivity is significantly improved through filter. In addition, a method of using He-Ne laser transmission light spot size to judge whether optical breakdown phenomenon happens, is also developed. This method is convenient and accurate, and can effectively reduce the error caused by naked eye observation.
