Abstract

The invention provides a fully polarization-maintaining active tracking fiber optic comb light source, which mainly solves the problem that the existing methods are sensitive to temperature and vibration; The frequency locking is changed from passive to active, which greatly enhances the anti-jamming ability, and at the same time realizes the function of active tracking and adjustable frequency.

Description

technical field [0001] The invention relates to a fully polarization-maintaining active tracking optical fiber comb light source, belonging to the technical field of lasers. Background technique [0002] After the femtosecond laser is frequency-locked and carrier-phase-locked, it can generate time-domain ultrashort pulse signals with very stable interval, amplitude and power. The pulse sequence has a rich Fourier transform spectrum, which can realize microwave frequency and optical Frequency direct connection. Direct absolute measurement of all optical frequencies from the near-infrared to the visible region can be realized with a single mode-locked femtosecond pulsed laser. This achievement is recognized as a revolutionary breakthrough in the field of optical frequency measurement. Comb optical frequency generator based on mode-locked femtosecond pulsed laser technology is considered as an optical gear to realize the transmission of optical frequency and microwave frequenc...
