Researchers from the National University of Defense Technology have developed a novel composite fiber Bragg grating using ...

This technology could help overcome the long-standing power ceiling for thulium fiber lasers, especially in inband-pumped architectures. By enabling robust, high-efficiency stripping at challenging ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

From precision machining to advanced microscopy, the demand for higher-power, ultrafast lasers continues to grow. Traditionally, researchers have relied on single-mode fibers to build these lasers, ...
