We describe configurations of a novel synchronously pumped femtosecond optical parametric oscillator based on the crystal RbTiOAsO(4) and operating with a signal-pulse-repetition frequency as high as 344 MHz. Average signal powers as high as 600 mW and pulse durations of 78 fs are demonstrated at a wavelength of 1.25 microm, and a characterization of the signal output using frequency-resolved optical gating implies asymmetric near-sech(2)(t) intensity-profile pulses with significant amounts of spectral cubic phase.
我们描述了一种基于晶体RbTiOAsO(4)的新型同步泵浦飞秒光学参量振荡器的配置，其信号脉冲重复频率高达344 MHz。在1.25微米波长处，展示了高达600毫瓦的平均信号功率和78飞秒的脉冲持续时间，并且使用频率分辨光学门控对信号输出进行的表征表明，其强度分布脉冲具有不对称的近双曲正割平方（sech(2)(t)）形状，且含有大量光谱立方相位。
