Nd3+-doped phosphate fibers for 0.9 μm single-frequency lasers: machine learning-driven compositional design for suppressing competitive emission
{{output}}
The 0.9 μm single-frequency fiber laser has emerged as a promising source for doubling frequency to generate blue lasers, which are essential for applications in underwater communication, detection, and laser display. However, the 4F3/2→4I9/2 transition at 0... ...
