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.
Semiconductor saturable absorber mirror (SESAM) is the core device for mode-locking to generate ultrashort pulses, especially picosecond pulses. This is a nonlinear light absorption structure that combines a mirror structure and a saturable absorber. Relatively weak pulses can be suppressed, and the pulses can be attenuated in a way that reduces their duration. At present, with the development of microfabrication industry at home and abroad, the demand for ultrashort pulses, especially picosecond pulsed lasers, is increasing, and the demand for SESAM is also increasing.

Compared with traditional technologies, the advantages of fiber lasers in beam quality, depth of focus and dynamic parameter adjustment performance have been fully recognized. Coupled with the advantages of electro-optical conversion efficiency, process versatility, reliability and cost, the application level of fiber lasers in medical device manufacturing (especially in fine cutting and micro welding) has been continuously improved.

A giant leap is taking place in mobility. This is true whether in the automotive sector, where autonomous driving solutions are being developed, or in industrial applications using robotics and automated guided vehicles. The various components in the whole system must cooperate with each other and complement each other. The main goal is to create a seamless 3D view around the vehicle, use this image to calculate object distances and initiate the next move of the vehicle with the help of special algorithms.
