Pulsed Erbium-doped Fiber Amplifier Manufacturers

Welcome to our booth Beijing National Convention Center,Booth:C71-2

When linearly polarized light is incident precisely along one of the principal axes (slow axis or fast axis), due to the huge difference in propagation constants between the two orthogonal polarization components, almost no energy coupling occurs between them, thereby maintaining the incident polarization state.

Fiber lasers refer to lasers that use rare-earth-doped glass fibers as gain media. Fiber lasers can be developed on the basis of fiber amplifiers: high power density is easily formed in the fiber under the action of pump light, resulting in laser working material. The energy level "number inversion" can form laser oscillation output when a positive feedback loop (form a resonant cavity) is properly added.

Fluorescence imaging has been widely used in biomedical imaging and clinical intraoperative navigation. When fluorescence propagates in biological media, absorption attenuation and scattering disturbance will cause fluorescence energy loss and signal-to-noise ratio decrease, respectively. Generally speaking, the degree of absorption loss determines whether we can "see", and the number of scattered photons determines whether we can "see clearly". In addition, the autofluorescence of some biomolecules and signal light are collected by the imaging system and eventually become the background of the image. Therefore, for biofluorescence imaging, scientists are trying to find a perfect imaging window with low photon absorption and sufficient light scattering.

A giant leap is taking place in mobility. This is true whether in the automotive sector, where autonomous driving solutions are being developed, or in industrial applications using robotics and automated guided vehicles. The various components in the whole system must cooperate with each other and complement each other. The main goal is to create a seamless 3D view around the vehicle, use this image to calculate object distances and initiate the next move of the vehicle with the help of special algorithms.
