In this paper , Fabry-Pérot laser diode ( FP-LD) based pulse generation with wavelength continuously tunable is demonstrated .Two topics are focused including ① a self-seeding system for continuous and widely wavelength-tunable optical short pulse generation .The side mode suppression ratio (SMSR) of greater than 37 dB is achieved across the wavelength range of 48 nm, at a constant repetition frequency of 2.5 GHz;②an ex-ternal-injection seeding scheme with selected wavelength feedback to the master FP laser diode for wavelength tunable optical short pulse generation .SMSR higher than 31 dB over a wavelength tuning range of 20 .4 nm have been obtained .The system is simple , and can be operated at arbitrary repetition frequency .
