Nanosecond Pulse Laser Manufacturers

Optical fibers are made of glass or plastic. Most are about the diameter of a human hair, and they can be many miles long. Light travels along the center of the fiber from one end to the other, and a signal can be applied. Fiber optic systems are superior to metal conductors in many applications. Their biggest advantage is bandwidth. Because of the wavelength of light, signals containing more information can be transmitted than metal conductors (even coaxial conductors

Laser distance measuring is measured using a laser as a light source.It is divided into continuous laser and pulse laser according to the mode of laser operation.Gas lasers like helium-neon, argon ion, krypton cadmium and so on work in a continuous output state for phase laser ranging, dual heterogeneous GaAs semiconductor laser for infrared ranging; solid laser such as ruby, neodymium glass, for pulse laser ranging.Laser rangefinder due to the characteristics of good monochromy and strong orientation of laser, coupled with the semiconductor integration of electronic lines, compared with the photoelectric rangefinder, it can not only work day and night, but also improve the rangefinder accuracy.

A revolutionary technology allows scientists to observe the interior of instantaneous particles called excitons (Exciton) at close range in an unparalleled way. Excitons describe the bound state of a pair of electrons and holes that are attracted to each other by electrostatic Coulomb interaction. They can be regarded as electrically neutral quasi-particles that exist in insulators, semiconductors and some liquids. They are condensed matter physics. The basic unit that transfers energy without transferring charge.

Raman fiber amplifier (RFA) is an important part of dense wavelength division multiplexing (DWDM) communication system. In many nonlinear optical media, the scattering of pump light with a shorter wavelength causes a small part of the incident power to be transferred to another beam whose frequency is shifted down. The amount of frequency shift down is determined by the vibration mode of the medium. This process is called pulling Mann effect. If a weak signal and a strong pump light wave are simultaneously transmitted in the fiber, and the weak signal wavelength is placed within the Raman gain bandwidth of the pump light, the weak signal light can be amplified. This mechanism is based on stimulated Raman scattering The optical amplifier is called RFA.
