It has a tuning bandwidth of 50nm in the 850nm band and a tuning bandwidth of 60nm in the 1060nm band. It can also provide a tuning bandwidth of 70~80nm according to customer requirements. The frequency selection device of this series of lasers is a tuned high-speed narrow-band AOTF with active temperature control. This guarantees the very high scanning speed of this series of frequency-swept lasers, the fastest scanning speed can reach 7us. In addition, AOTF also guarantees very high linearity of scanning. The wavelength resolution of this series of swept frequency tunable lasers is 0.05nm. AOTF's radio frequency control signal can be programmed before leaving the factory according to the customer's special timing requirements for wavelength scanning. The active temperature control technology of AOTF ensures the long life of the swept frequency tunable laser, high wavelength output stability, and high wavelength repeatability. The specially designed high-speed and high-precision closed-loop power control system guarantees very high power stability during the high-speed wavelength scanning (100,000 nm/s.) of the full spectrum. The carefully designed external cavity structure ensures extremely high spectral purity in the entire scanning band, and the side mode suppression ratio reaches -50 dB. This series of swept frequency tunable lasers are widely used in (optical coherence tomography) optical coherence tomography (OCT), interferometry, spectroscopy, optical fiber sensing and other fields.
