We are grateful to Ballato et al. [Opt. Mater. Express 13, 2338 (2023)10.1364/OME.491887] for their comment on our recently published paper. The optical model and simulation of optical fiber materials are important to design new materials systems and to further improve the fiber laser performance. However, accurate calculation of the non-crystal fiber materials is still challenging, both from the methodology and from the needed calculating resources. The recently published paper [Opt. Mater. Express 13, 935 (2023)10.1364/OME.485138] has sparked interest, which gives us the opportunity to explain the difference between the modeled data and the well-established experimental results.
