Semiconductor lasers are commonly known as laser diodes. They are called semiconductor lasers because of the characteristics of using semiconductor materials as working materials. The semiconductor laser is composed of a fiber-coupled semiconductor laser module, beam combining device, laser energy transmission cable, power supply system, control system and mechanical structure....

DFB: Distributed Feedback Laser.

Optical fiber array, using a V-groove (V-Groove) substrate, a bundle of optical fibers or an optical fiber ribbon is installed on the substrate at specified intervals to form an array.

As anyone who watched Clarkson’s Farm knows, farming is a costly business, and the profits can be slim. If Britain’s farmers are to thrive at a time of shrinking subsidies and increased competition, they need to minimise their capital outlay and ongoing costs. The more they can do to keep existing machinery running, and performing as well as it should, the better.

In the optical fiber communication network, the most commonly used laser is the distributed feedback (DFB) laser, which is a single longitudinal mode or single frequency semiconductor laser. The single frequency laser refers to a laser with only one longitudinal mode (spectral line) spectrum characteristic of the semiconductor laser. It can work in the third generation optical ...

A giant leap is taking place in mobility. This is true whether in the automotive sector, where autonomous driving solutions are being developed, or in industrial applications using robotics and automated guided vehicles. The various components in the whole system must cooperate with each other and complement each other. The main goal is to create a seamless 3D view around the v...

Although both spectrum and spectrum are electromagnetic spectra, the analysis methods and testing instruments of spectrum and spectrum are quite different because of the difference of frequency. Some problems are difficult to solve in the optical domain, but it is easier to solve them by frequency conversion to the electrical domain.

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, n...
