Based on a supercontinuum source at 1um wavelength range, we report a difference frequency generation (DFG) comb working at the wavelength of Mid-IR. Because the SC was generated from the PCF with normal dispersion, the SC pulse was linearly chirped. By dividing the SC pulse into two pulses with the wavelength range of 900-1000 nm and 1000-1200 nm, and carefully adjusting a delay line, the Mid-IR light generated from a PPMgSLT crystal was continually tuned from 2.9-4.7 um.
