Up to ~520 μJ broadband mid-infrared (IR) supercontinuum (SC) generation in telecommunicationmultimode fiber (MMF) directly pumped by a 2.054 μm nanosecond Q-switched Tm,Ho:YVO<sub>4</sub> laser isdemonstrated. An average output power of 3.64 W is obtained in the band of ~1900 to ~2600 nm, andthe corresponding optic-to-optic conversion efficiency is 67% by considering the coupling efficiency. Thespectrum has extremely high flatness with negligible intensity variation (<2%) in the wavelength intervalof ~2070 to ~2475 nm. The SC long-wavelength edge is limited by the silicon glass material loss, andby optimizing the MMF length, the SC spectrum could extend out to ∼2.6 μm. The output SC pulseshapes are measured at different output powers, and no splits are found. The SC laser beam is nearlydiffraction limited with an M<sup>2</sup> =1.15 in 2.1 μm measured by the traveling knife-edge method, and thelaser beam spot is monitored by an infrared vidicon camera
