Semiconductor lasers are a type of lasers that mature earlier and are developing rapidly. Because of its wide wavelength range, simple manufacture, low cost, easy mass production, and because of its small size, light weight, and long life, its variety develops quickly and its application The range i......

Fiber Laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. Fiber lasers can be developed on the basis of fiber amplifiers. High power density is easily formed in the fiber under the action of pump light, resulting in laser The laser energy level of the working substance......

Fiber optic module can be divided into fiber optical receiver module, fiber optical transmission module, fiber optical transceiver module and fiber optical transponder module.

For spectral synthesis technology, increasing the number of synthesized laser sub-beams is one of the important ways to increase the synthesis power. Expanding the spectral range of fiber lasers will help increase the number of spectral synthesis laser sub-beams and increase the spectral synthesis p......

The team of Professor Rao Yunjiang of the Key Laboratory of Optical Fiber Sensing and Communications of the Ministry of Education, University of Electronic Science and Technology of China, based on the main oscillation power amplification technology, realized for the first time a multimode fiber ran......

A femtosecond laser is an "ultrashort pulse light" generating device that emits light only for an ultrashort time of about one-gigasecond. Fei is the abbreviation of Femto, the prefix of the International System of Units, and 1 femtosecond = 1×10^-15 seconds. The so-called pulsed light emits light......
