  • 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.

  • What are the principles and differences between 1st-order Raman Amplifier and 2nd-order Raman Amplifier?

    1st-order Raman spectroscopy utilizes stimulated Raman scattering in silica optical fibers. 140 nm pump light directly amplifies C-band signal light (1530-1565 nm). The pump light vibrates and scatters in the fiber, transferring energy to the frequency of the signal light.

  • High-performance visible light holmium-doped all-fiber laser

    Directly generating visible light from compact all-fiber lasers while maintaining high output characteristics has always been a research topic in laser technology. Here, Ji et al. proposed a method to develop dual-wavelength lasers using the excitation mechanism in holmium-doped ZBLAN fluoride glass fibers, and experimentally achieved high output performance of all-fiber lasers, especially operating in the deep red band under 640 nm pumping. Notably, a maximum continuous wave output power of 271 mW was achieved at 750 nm with a slope efficiency of 45.1%, which is the highest direct output power recorded in all-fiber lasers with a core diameter of less than 10 μm in the deep red band.

  • The main function of optical fiber temperature measurement

    Optical fiber temperature measurement technology is a new technology that has only been developed in recent years, and has gradually revealed some excellent characteristics. But just like other new technologies, optical fiber temperature measurement technology is not a panacea. It is not used to replace traditional methods, but to supplement and improve traditional temperature measurement methods. By giving full play to its strengths, new temperature measurement solutions and technical applications can be created.

  • Why are the classic infrared wavelengths 808nm, 1064nm, and 1550nm?

    The basic components of a laser can be divided into three parts: a pump source (which provides energy to achieve population inversion in the working medium); a working medium (which has a suitable energy level structure that enables population inversion under the action of the pump, allowing electrons to transition from high energy levels to the lower level and release energy in the form of photons); and a resonant cavity.
