    Five trends in the fiber laser market are suggested by the Institute
    The successful development of Lock Martin‘s latest 30,000 watt laser weapon can not be separated from the emergence and significant development of fiber laser technology. Fiber laser is a kind of laser which uses rare earth doped glass fiber as gain medium. Fiber laser can be developed on the basis of fiber amplifier. Different from the traditional gas laser, the fiber laser u...

    fiber-optic laser
    The fiber laser uses a rare earth doped fiber as the gain medium, and the pump light forms a high power density in the core, resulting in a "particle number reversal" of the doped ion level. When a positive feedback loop (constituting a resonant cavity) is properly added, A laser output is produced.

  • Classification of optical fiber temperature sensor
    Classification of optical fiber temperature sensor
    The fiber optic temperature sensor is a sensing device that analyzes the spectrum of the fiber transmission to understand the real-time temperature by using the principle that the spectrum absorbed by some substances changes with temperature.

  • Strain characteristics of pressure sensors
    Strain characteristics of pressure sensors
    The pressure sensor has a measuring range that is twice as large as an inductive sensor. Not only can metal targets be detected, but also dielectrics such as paper, glass, wood and plastic, and even wall or paper. There are also trembling measurements and burglar alarms for humans, since the human body is equivalent to an electrical conductor at low frequencies.

  • How the pressure transmitter works
    How the pressure transmitter works
    The electrical components that the pressure transmitter feels pressure are generally resistance strain gauges, which are sensitive devices that convert the pressure on the device under test into an electrical signal. The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. The metal resistance strain gauge has two kinds o...
