In the last two decades, the rapid advancement in applications such as environmental monitoring, medical diagnostics, and global positioning has intensified the focus on developing novel mid-IR light sources. Fiber-based mid-IR lasers, which operate beyond 2.5 μm, have emerged as particularly promising high-brightness light sources. However, extending laser generation into the mid-IR wavelength range presents significant challenges, primarily due to the extreme absorption in silica fibers, whic...
