Fiber-based supercontinuum offer broad spectral bandwidth, high brightness, and excellent spatial coherence, showing great promise in applications such as electro-optical countermeasures, gas sensing, and optical coherence tomography. To address the diverse performance requirements of supercontinuum imposed by different application scenarios, this paper reviewed recent advances in three key directions of fiber-based supercontinuum: power scaling, long wave extension, and low noise research. The technical approaches tailored to enhance each specific performance metric were summarized, and an outlook on future developments was provided, aiming to serve as a reference for the development and application of high-performance supercontinuum.
