摘要:

提出了一种基于周期极化铌酸锂的中红外波段高功率光参量振荡器频率梳。该系统由中心波长为1.07 μ m的10 W飞秒Yb:光纤激光器同步泵浦,并对信号进行单共振。闲频(信号)波长可在2.8 ~ 4.8 μ m(1.76 ~ 1.37 μ m)范围内连续调谐,同时带宽高达0.3 μ m,最大平均闲频输出功率为1.50 W。我们还证明了稳定的梳的性能,通过记录外差拍与窄线宽二极管激光器。该OPO是中红外频率梳光谱的理想光源。

英文摘要:

We present a high-power optical parametric oscillator-based frequency comb in the mid-infrared wavelength region using periodically poled lithium niobate. The system is synchronously pumped by a 10-W femtosecond Yb:fiber laser centered at 1.07 um and is singly resonant for the signal. The idler (signal) wavelength can be continuously tuned from 2.8 to 4.8 um (1.76 to 1.37 um) with a simultaneous bandwidth as high as 0.3 um and a maximum average idler output power of 1.50 W. We also demonstrate the performance of the stabilized comb by recording the heterodyne beat with a narrow-linewidth diode laser. This OPO is an ideal source for frequency comb spectroscopy in the mid-IR.
