Supercontinuum (SC) sources covering near‐infrared and midinfrared region have attracted enormous interest and found significant applications in tissue imaging, sensing, spectroscopy, defense, and environmental monitoring. Herein, an 8.45 W all‐fiber ultraflat SC source with a spectral range of 1.01–4.05 μm using a flat high‐power 1.9–2.7 μm SC fiber source to pump a piece of fluorotellurite fiber is presented. The SC spectrum exhibits a 3 dB bandwidth of 1850 nm, ranging from 1870 to 3720 nm, and a 10 dB bandwidth of 2770 nm, ranging from 1120 to 3890 nm. The measured power stability is 0.19% (root mean square) for 5 h of continuous operation, proving the excellent power stability of the system. To the best of knowledge, the SC spectrum exhibits the widest reported 3 and 10 dB bandwidths for 1–4 μm SC sources.
