This product is an ultra-low phase noise optical frequency comb, featuring a fully polarization-maintaining structure, high integration, independent intellectual property rights, and domestically produced core components. The device supports one-button startup, and its ultra-high precision in frequency accuracy and stability make it widely applicable in spectroscopy, ultra-low noise microwave source generation, frequency measurement and distribution, as well as other metrology fields.
The oscillator in this product utilizes Figure-9 mode-locking technology, ensuring the output femtosecond laser exhibits excellent stability and low noise characteristics. Through optimized phase-locked loop electrical design, it can rapidly lock the frequency to either an RF reference or an optical reference, providing high-precision frequency stability and supporting multiple output paths. The output spectral range can extend from 1260nm to 1630nm. This product also offers customized services for parameters such as repetition frequency and pre-specified spectral ranges.
