Haoyuan Optoelectronics specializes in providing various Swept Wavelength Tunable Lasers (Swept Wavelength Tunable Lasers, or Broadsweepers), which are external cavity tunable semiconductor lasers with fast wavelength scanning function and high tuning accuracy. , high wavelength repeatability. It has a 50nm tuning bandwidth in the 850nm band and a 60nm tuning bandwidth 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 ensures a very high scanning speed for this series of swept lasers, with the fastest scanning speed reaching 7us. In addition, AOTF also ensures very high linearity of scanning. This series of swept frequency tunable lasers has a wavelength resolution of 0.05nm. AOTF's radio frequency control signals can be programmed at the factory according to customers' 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 ensures very high power stability during full-spectrum high-speed wavelength scanning (100,000 nm/s.). The carefully designed external cavity structure ensures extremely high spectral purity in the entire scanning band, with a side mode suppression ratio of -50 dB. This series of swept frequency tunable lasers are widely used in optical coherence tomography (OCT), interferometry, spectroscopy, fiber optic sensing and other fields.
