DWDM: Dense Wavelength Division Multiplexing is the ability to combine a group of optical wavelengths and use a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.

In various optical fiber interference instruments, in order to obtain the maximum coherence efficiency, the polarization state of the optical fiber propagating light is required to be very stable. The transmission of light in a single-mode fiber is actually two orthogonal polarization fundamental modes. When the optical fiber is an ideal optical fiber, the transmitted fundamental mode is two orthogonal double degenerate states, and the actual optical fiber is drawn due to There will be unavoidable defects, which will destroy the double degenerate state and cause the polarization state of the transmitted light to change, and this effect will become more and more obvious as the length of the fiber grows. At this time, the best way is to use Polarization maintaining fiber.

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 type is power-type lasers for the purpose of directly using the optical power of the output laser.

An international consortium led by the UK's National Physical Laboratory has set a new record for comparing ultra-stable lasers at long distances by metering a fibre network. A related research paper was published in the journal Nature Communications.

Recently, ResearchAndMarkets released the global industrial laser market analysis report. The global industrial laser market was valued at USD 6.89 billion in 2021 and is expected to grow to USD 15.07 billion by 2027.
