Optical Coherence Tomography (OCT) is a low-loss, high-resolution, non-invasive medical and imaging technology developed in the early 1990s. Its principle is similar to ultrasound imaging, the difference is that it uses light instead of sound.
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.

Furukawa Electric and Fujitsu Optical Devices (FOC) have agreed to cooperate in the development of integrated equipment for next-generation high-capacity optical communications. The two companies stated that they will use their respective advantages to develop high-capacity, compact, and low-power devices for next-generation communication networks to meet the demand for solutions in the Asian region.
In the industrial laser application, people usually use 915nm pumping in the past, but with the rapid development of fiber lasers, the market demand for higher power has become more and more prominent, and competition is becoming increasingly fierce. The 915nm wavelength has lower absorption efficient which brought double obstacles in cost and technical, limiting the development of high-power and low-cost fiber coupled laser modules.
Everyone must have heard the slogan "femtosecond laser for myopia", but I believe many people don't know what femtosecond laser is. Similarly, there are nanosecond laser and picosecond laser. What's the difference between these strange seconds and our common lasers?
