White lasers are promising illuminants for emerging visible light communication, which can overcome bottlenecks of lower energy conversion efficiencies and output powers in traditional white light‐emitting (WLE) diodes. However, optical gain materials for white lasers are suffering from great challenges of material growth and growth‐compatible cavity structure where lasing of all three elementary colors can be supported simultaneously. Here, an exquisite physical strategy is demonstrated to realize simultaneous red, green, and blue (RGB) upconversion (UC) photoluminescence for white light modulation for the first time, namely using dual lasers at 850 and 980 nm to stimulate easy‐fabricated glass ceramics (GCs) fiber laser materials (Pr3+ single‐doped germanium oxyfluoride GCs). It is shown that tailorable white light is much more sensitive to lower dopant concentration for GCs than that for glass. Furthermore, compared to glass, UC fluorescence intensities in GCs have approximately two orders of magnitude enhancement. The feasibility of the judicious dual‐lasers excitation tactic is validated for high efficacious RGB fluorescence emission for white light from Pr3+ single‐doped GCs via electronics transition dynamics and theoretical calculations. The white light emission from Pr3+ single‐doped GCs, adjusted by simultaneous dual‐lasers excitation, may open a novel door to develop white light GCs fiber lasers for application in future wireless communication.

通过同时进行双激光激发，从Pr3 +单掺杂玻璃陶瓷获得可定制的上转换白光发射
白激光是新兴的可见光通信的有希望的光源，它可以克服传统白光（WLE）二极管中较低的能量转换效率和输出功率的瓶颈。但是，用于白光激光器的光增益材料面临着材料生长和与生长兼容的腔结构的巨大挑战，在这种结构中，可以同时支持所有三种基本颜色的激光发射。此处展示了一种精妙的物理策略，首次实现了同时进行红，绿和蓝（RGB）上转换（UC）光致发光以进行白光调制，即使用850和980 nm的双激光激发易加工的玻璃陶瓷（GCs）光纤激光材料（Pr 3+单掺杂氟氧化锗GC）。结果表明，与玻璃相比，可定制的白光对GC较低的掺杂剂浓度更敏感。此外，与玻璃相比，GC中的UC荧光强度大约提高了两个数量级。通过电子跃迁动力学和理论计算，验证了明智的双激光激发策略的可行性，从而可用于Pr 3+单掺杂GC的白光高效RGB荧光发射。Pr 3+单掺杂GC发出的白光通过同时进行双激光激发进行调节，可能为开发白光GC光纤激光器打开一扇崭新的大门，可将其应用于未来的无线通信中。
