Enhanced beam quality of high-energy lasers utilizing fused silica as an all-solid-state SBS-PCM
Beam quality is critical for laser applications in both scientific and industrial fields. Stimulated Brillouin scattering phase conjugate mirror (SBS-PCM) serves as an effective beam cleanup scheme due to its phase conjugation properties. In this work, a SBS-PCM using fused silica was constructed and employed in a double-pass amplifier setup. With an input energy of 75.2 mJ, the system achieved a maximum magnification of approximately 9 times, resulting in an output energy of 672 mJ. Comparative analysis with a high-reflection mirror revealed that the SBS-PCM effectively mitigated unfavorable diffraction patterns induced by the hard-edge aperture in the near-field pattern, improving the beam quality factor from 1.23 to 1.085 times the diffraction limit. Additionally, the coefficient of determination (R2) of the beam profile improved by 2.18 % compared to that of the high-reflection mirror. These results indicate that the free-space all-solid-state SBS-PCM can provide a promising approach to improving beam quality for high-power laser systems.
