Fiber-based supercontinuum sources 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 fiber-based supercontinuum imposed by different application scenarios, this review focuses on three key directions: power scaling, mid-infrared spectral extension, and suppression of intensity noise. We summarize recent advances in fiber-based supercontinuum generation, outline technical approaches tailored to enhance each specific performance metric, and provide an outlook on future developments, aiming to serve as a reference for the development and application of high-performance.
