摘　　要：The flexible delivery of single-frequency lasers is far more challenging than that of conventional lasers due to the onset of stimulated Brillouin scattering (SBS).Here we present the successful delivery of 100 W single-frequency laser power through 100 m of anti-resonant hollow-core fiber (AR-HCF) in an all-fiber configuration,with the absence of SBS.By employing a custom-designed AR-HCF with a mode-field diameter matching that of a large-mode-area panda fiber the system achieves high coupling efficiency without the need for free-space components or fiber post-processing.The AR-HCF attains a transmission efficiency of 92%,delivering an output power of 100.3 W with a beam quality factor(M^(2)) of 1.22.The absence of SBS is confirmed through monitoring backward light,which shows no increase in intensity This all-fiber architecture ensures high stability,compactness and efficiency,potentially expanding the application scope of single-frequency lasers in high-precision metrology,optical communication,light detection and ranging systems gravitational wave detection and other advanced applications.
