We present repetition rate multiplied pulse train generation from a 10 GHz mode-locked laser by line-by-line spectral coding using a simple intensity and/or phase mask. We generate 20 ~ 160 GHz pulses with 10 GHz step. Such high repetition rate multiplication is achieved by combining both spectral intensity and phase coding. For the generated pulses, the optical spectra and autocorrelation traces are examined.
