  • Fiber Optic Sensor
    Fiber Optic Sensor
    An optical fiber sensor is a sensor that converts the state of the measured object into a measurable light signal. The working principle of the optical fiber sensor is to send the incident light beam from the light source into the modulator through the optical fiber. The interaction between the modulator and the external measured parameters determines the optical properties of ...

    laser distance measurng
    laser distance measurng uses a laser as a light source for ranging. According to the way the laser works, it is divided into continuous optical devices and pulse lasers. Ammonia, gas ions, atmosphere temperature and other gas detectors work in a continuous forward state, used for phase laser ranging, dual heterogeneous semiconductor lasers, used for infrared ranging, ruby, gold...

  • Linewidth Characteristics of Single-Frequency Fiber Lasers
    Linewidth Characteristics of Single-Frequency Fiber Lasers
    Single-frequency fiber lasers have a very narrow limit linewidth, and their spectral line shape is Lorentz type, which is significantly different from single-frequency semiconductors. The reason is that single-frequency fiber lasers have longer laser resonant cavities and longer photon lifetimes in the cavity. This means that single-frequency fiber lasers have lower phase noise...

    Near-infrared to mid-infrared tunable lasers
    Different spectral range definitions. Generally speaking, when people talk about infrared light sources, they are referring to light with vacuum wavelengths greater than ~700–800 nm (the upper limit of the visible wavelength range). The specific wavelength lower limit is not clearly defined in this description because the human eye‘s perception of infrared slowly decreases ...
