780nm Femtosecond Pulse Fiber Laser Manufacturers

ASE light source is specially designed for laboratory experiment and production. The main part of the light source is gain medium erbium-doped fiber and high-performance pump laser. The unique ATC and APC circuits ensure the stability of the output power by controlling the output of the pump laser. By adjusting APC, the output power can be adjusted within a certain range. Simple and intelligent operation and remote control.

Compared with traditional oxyacetylene, plasma and other cutting processes, laser cutting has the advantages of fast cutting speed, narrow slit, small heat affected zone, good verticality of slit edge, smooth cutting edge, and many kinds of materials that can be cut by laser. Laser cutting technology has been widely used in the fields of automobiles, machinery, electricity, hardware and electrical appliances.

Wavelength division multiplexing refers to a technology in which signals of different wavelengths are transmitted together and separated again. At most, it is used in optical fiber communication to transmit data in multiple channels with slightly different wavelengths. Using this method can greatly improve the transmission capacity of the optical fiber link, and the use efficiency can be improved by combining active devices such as optical fiber amplifiers. In addition to applications in telecommunications, wavelength division multiplexing can also be applied to the case where a single fiber controls multiple fiber optic sensors.

In data centers, optical modules exist everywhere, but few people mention them. In fact, optical modules are already the most widely used products in data centers. Today's data centers are basically optical fiber interconnection, and the situation of cable interconnection has become less and less. Therefore, without optical modules, data centers cannot operate at all. The optical module converts electrical signals into optical signals at the sending end through photoelectric conversion, and then transmits through optical fibers, and then converts the optical signals into electrical signals at the receiving end. That is to say, any optical module has two parts: transmitting and receiving. The function is to do photoelectric conversion and electro-optical conversion, so that the optical modules are inseparable from the equipment at both ends of the network. There are thousands of devices in a medium-sized data center.

Laser is considered to be one of the greatest inventions of mankind in the twentieth century, and its appearance has strongly promoted the progress of detection, communication, processing, display and other fields. Semiconductor lasers are a class of lasers that mature earlier and progress faster. They have the characteristics of small size, high efficiency, low cost, and long life, so they are widely used. In the early years, infrared lasers based on GaAsInP systems laid the cornerstone of the information revolution.
