主　　题：tunable power tuning 

摘      要：Ultrafast visible radiation is of great importance for many applications ranging from spectroscopy to *** some regions in the visible range are not covered by laser gain media,optical parametric oscillators offer an added *** a high-power broadband laser source,the ability to rapidly tune the frequency of pulses with high-power spectral density offers an extra benefit for experiments such as multicolor spectroscopy or ***,we demonstrate a broadband,high-power,rapidly tunable femtosecond noncollinear optical parametric oscillator with a signal tuning range of 440–720 nm in the visible *** oscillator is pumped by the third harmonic of an Yb-fiber laser at 345 nm with a repetition rate of 50.2 ***,the signal wavelength is tuned by changing the cavity length only,and output powers up to 452 m W and pulse durations down to 268 fs are *** is,to the best of our knowledge,the first demonstration of a quickly tunable femtosecond optical parametric oscillator that covers nearly the entire visible spectral range with high output power.
