    ASE light source
    The main body of the ASE light source is composed of high-performance pump lasers, which have the function of gain medium erbium-doped fibers. The circuit mainly consists of two types of circuits: ATC and APC. The reason why the ASE light source has excellent power output stability is because the pump laser is controlled through these two circuits to complete.

    The transmission distance of the optical module refers to the distance over which the optical signal can be directly transmitted without relay amplification. It is divided into three types: short-distance, medium-distance, and long-distance. Generally speaking, 2km and below are short distances, 10-20km are medium distances, and 30km, 40km and above are long distances. Optical ...

    What is the difference between single-mode and multi-mode fiber lasers
    Fiber Laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. 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 The laser energy level of the working substance is "population inversion", and when a positive feedback loop (to form a resonan...

    The principle of laser cleaning
    In the mid-1980s, Beklemyshev, Allrn and other scientists combined laser technology and cleaning technology for practical work needs and conducted related research. Since then, the technical concept of laser cleaning (Laser Cleanning) was born. It is well known that the relationship between pollutants and substrates The binding force is divided into covalent bond, double dipole...

    Fiber cut-off wavelength
    The fiber cut-off wavelength is to ensure that only one mode exists in the fiber. One of the main transmission characteristics of single-mode fiber is the cut-off wavelength, which is of great significance for fiber optic cable manufacturers and users of fiber optic cables to design and use fiber optic transmission systems.
