  • 1.5 μm Band Single Frequency Fiber Laser
    1.5 μm Band Single Frequency Fiber Laser
    Single-frequency lasers based on Er3+-doped or Er3+/Yb3+ co-doped gain fibers mainly work in the 1.5 μm band (C-band: 1530-1565 nm) and part of the L-band (1565-1625 nm). Its wavelength is in the C window of optical fiber communication, which makes the 1.5 μm band single-frequency fiber laser with narrow linewidth and low noise characteristics very important in coherent optical...

  • What is an eye diagram
    What is an eye diagram
    The eye diagram is a series of digital signals accumulated and displayed on the oscilloscope. It contains a wealth of information. From the eye diagram, the influence of intersymbol crosstalk and noise can be observed, which reflects the overall characteristics of the digital signal, so as to estimate the system optimization. Therefore, eye diagram analysis is the core of signa...

  • Multi-pass fiber amplifier
    Multi-pass fiber amplifier
    Definition: An amplifier with multiple channels in a gain medium. The gain medium of an optical amplifier can only achieve a limited gain. One approach achieves higher gain by geometrically setting up light so that it passes through multiple channels as it passes through the amplifier, known as a multipass amplifier. The simplest is a two-pass amplifier, where the beam passes t...

    The principle of laser cleaning
    Laser cleaning is the use of laser beams that have the characteristics of large energy density, controllable direction and strong convergence ability, so that the bonding force between the pollutants and the substrate is destroyed or the pollutants are directly vaporized to decontaminate and reduce pollutants. The bonding strength with the matrix, and then achieve the effect of...
