摘　　要：A femtosecond LBO optical parametric oscillator(OPO)with widely adjustable repetition rate by fractionally decrement of the cavity length is demonstrated.The repetition rate of 755 MHz to 1.43 GHz at an interval of 75.5 MHz is realized,which is 10 to 19 times that of the pump laser.The properties of output signal at 750 nm at different repetition rates are studied.The power of signal decreases with increasing the repetition rate.The maximum power of 194 mW at the repetition rate of 755 MHz and the minimum power of 22 mW at repetition rate of 1.43 GHz for the signal at 750 nm are obtained for the pump power of 3 W.A femtosecond LBO optical parametric oscillator(OPO) with widely adjustable repetition rate by fractionally decrement of the cavity length is demonstrated.
