We　demonstrated　a　repetition-rate-tunable　second　harmonic　mode-locked　optically　pumped　semiconductor　disk　laser　(OP-SDL),　and　the　tuning　range　was　from　1.168　GHz　to　1.25　GHz.　The　entire　tuning　process　was　continuous,　and　OP-SDL　was　always　in　a　mode-locked　working　state.　To　the　best　of　our　knowledge,　this　is　the　first　work　to　obtain　intracavity　repetition　rate　tunable　second　harmonic　laser　in　an　OP-SDL.　At　same　time,　the　repetition　rate　of　fundamental　wave　can　be　continuously　adjusted　from　1.16　GHz　to　1.66　GHz.　The　central　wavelengths　of　the　pulse　trains　were　around　971　nm,　and　the　highest　repetition　rate　signal-to-noise　ratio　was　more　than　60　dB,　indicating　that　the　mode-locked　pulses　were　stable.
