Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two ...

Abstract: Fiber Bragg gratings (FBGs) with significantly enhanced reflectivity in ring-core fibers (RCFs) were successfully inscribed by using a high-repetition-rate femtosecond laser and the ...

Abstract: Passive mode-locking plays a crucial role in generating ultrafast laser pulses and high-quality beams. However, traditional figure-of-eight laser cavities often require additional ...
