Transparent Nd 3+ ,Gd 3+ ‐codoped SrF 2 laser ceramic was fabricated by a single‐crystal ceramization (SCC) technique, and the fluorescence properties were also characterized. The results indicated that the SCC process would lead to reducing fluorescence properties of ceramic by re‐clustering small amount of Nd 3+ ions. In this study, the re‐clustering of Nd 3+ ions were addressed by a simple thermal drive‐induced grains regrowth (TDIGR) treatment. The properties of the Nd 3+ ,Gd 3+ ‐codoped SrF 2 laser ceramic undergo the TDIGR were improved and close to precursor Nd 3+ , Gd 3+ ‐codoped SrF 2 single crystal. Meanwhile, the transmittance of ceramic (T average@400‐1400nm ~ 92%) was hardly affected by the TDIGR treatment. Therefore, we have reasons to believe that the combination of SCC and TDIGR is a suitable approach to obtain high optical quality neodymium, buffer ion‐codoped alkaline‐earth fluoride (Nd 3+ ,B 3+ ‐codoped MF 2 ) laser ceramics.
