Semiconductor laser is a kind of laser developed in the 1960s, using semiconductor materials as working materials. Since the end of the 1970s, semiconductor lasers have clearly developed in two directions. One type is information-type lasers for the purpose of transmitting information, and the other......

When the incident light flux leaves from the illuminated surface or the incident surface of the medium to the other side, the ratio of the radiant energy projected and transmitted through the object to the total radiant energy projected on the object is called the transmittance of the object. The pe......

Optical fiber splice, which connects two optical fibers permanently or detachably, and has a splice part for protecting the components. The optical fiber splice is the end device of the optical fiber. The optical fiber connector is a physical interface used to connect an optical fiber cable. FC is ......

Ultrafast laser is a kind of laser based on SESAM, Kerr lens and other mode-locking technology, the pulse width is in the order of ps or even fs.

Single-frequency fiber lasers have unique properties such as ultra-narrow linewidth, adjustable frequency, ultra-long coherence length, and ultra-low noise. The FMCW technology on microwave radar can be used for ultra-high-precision coherent detection of ultra-long-distance targets. Change the marke......
