We demonstrate a low relative intensity noise (RIN) (⪅-125dBc/Hz from 1 MHz to 10MHz), Continuous Wave (CW) Supercontinuum (SC) generation in standard telecom fiber by using a low intensity noise 1064nm Ytterbium (Yb) doped fiber amplifier as pump source. The generated SC has ⪆8dB of RIN improvement (over a bandwidth of 300nm from 1400nm to 1700nm) when compared to the RIN of SC generated by a conventional Fiber Bragg Grating (FBG) cavity based Yb fiber pump laser. Integrated Root Mean Square (RMS) RIN of 0.16 % (from 1MHz to 10MHz) was better than the low noise CW supercontinua reported so far.
