背景技术Background technique

由于光学频率梳具有在时域上表现为超短激光脉冲序列、在频域上表现为梳状等间隔多光谱的特性,使其在精密光谱分析、绝对距离测量、激光波长校准、时频信号传递等领域得到了广泛应用。Because the optical frequency comb has the characteristics of ultra-short laser pulse sequence in the time domain and comb-shaped equal interval multi-spectrum in the frequency domain, it can be used in precision spectrum analysis, absolute distance measurement, laser wavelength calibration, time-frequency signal It has been widely used in transmission and other fields.

近年来,在精密光谱分析与绝对距离测量领域中,基于外差双光学频率梳的测量方法不断发展,已经成为其各自领域中的重要研究方向。频域方面,外差双光学频率梳之间各个梳齿的外差干涉信号呈等差数列分布,便于高精度的提取各个梳齿的干涉测量信息。时域方面,外差双光学频率梳之间各个脉冲的时间间隔周期性变化,其测量效果与脉冲扫描状态一致,可大幅节约测量时间。In recent years, in the fields of precision spectral analysis and absolute distance measurement, measurement methods based on heterodyne dual optical frequency combs have been continuously developed, and have become important research directions in their respective fields. In the frequency domain, the heterodyne interference signal of each comb tooth between the heterodyne dual optical frequency combs is distributed in an arithmetic sequence, which is convenient for extracting the interferometric information of each comb tooth with high precision. In the time domain, the time interval of each pulse between the heterodyne dual optical frequency combs changes periodically, and the measurement effect is consistent with the pulse scanning state, which can greatly save measurement time.

现有的外差双光学频率梳生成方法主要基于两套飞秒频率梳系统的互锁定控制。但该方法中两套飞秒频率梳系统的频率一致性受互锁定控制精度限制,同时其实现装置结构复杂、成本高,制约了精密光谱分析和绝对距离测量领域中基于外差双光学频率梳测量方法的进一步发展。另外,光学频率梳的光谱范围对上述领域的测量范围与精度具有决定性作用。因此,亟需一种大光谱范围、高频率一致性、低成本的外差双光学频率梳生成方法与装置。The existing heterodyne dual optical frequency comb generation method is mainly based on the interlocking control of two femtosecond frequency comb systems. However, the frequency consistency of the two femtosecond frequency comb systems in this method is limited by the precision of interlocking control. At the same time, the structure of the device is complex and the cost is high, which restricts the use of heterodyne dual optical frequency combs in the field of precision spectral analysis and absolute distance measurement. Further development of measurement methods. In addition, the spectral range of the optical frequency comb plays a decisive role in the measurement range and precision of the above-mentioned fields. Therefore, there is an urgent need for a large spectral range, high frequency consistency, and low-cost heterodyne dual optical frequency comb generation method and device.
