A monolithic 0– f scheme-based femtosecond optical frequency comb directly driven by a high-power Ti:sapphire laser oscillator is demonstrated. The spectrum covering from 650 nm to 950 nm is generated from the Ti:sapphire oscillator with a repetition rate of 170 MHz. The average output power up to 630 mW is delivered under the pump power of 4.5 W. A 44-dB signal-to-noise ratio (SNR) of the carrier-envelope phase offset (CEO) beat note is achieved under the resolution of 100 kHz and is long-term stabilized to a reference source at 20 MHz. The integrated phase noise (IPN) in the range from 1 Hz to 1 MHz is calculated to be 138 mrad, corresponding to the timing jitter of 63 as at the central wavelength of 790 nm.

由大功率Ti：Sapphire振荡器直接驱动的基于单片0–f方案的频率梳

演示了一种基于单片0-f方案的飞秒光学频率梳，该梳由高功率Ti：蓝宝石激光振荡器直接驱动。Ti：蓝宝石振荡器产生的重复频率为170 MHz，光谱范围从650 nm到950 nm。在4.5 W的泵浦功率下可提供高达630 mW的平均输出功率。在100的分辨率下，可实现44 dB的载波包络相位偏移（CEO）拍频音的信噪比（SNR） kHz，并长期稳定在20 MHz的参考源上。计算出从1 Hz到1 MHz范围内的积分相位噪声（IPN）为138 mrad，对应于中心波长790 nm处的63的定时抖动。
