The world’s most powerful laser system for industrial applications would be presented. Ytterbium fiber laser combines record 101.3 kW output power, continuous-wave operational mode and an excellent beam quality. Beam parameter product (BPP) does not exceed 16 mm x mrad, when we use 300 μm x 10 m feeding fiber, or near 25 mm x mrad, when fiber-to-fiber output coupler with 500 μm x 50 m process fiber is used. Emission wavelength is 1070 nm. High wall-plug efficiency 35.4%, compact laser cabinet and total weight less than 3600 kg open the new opportunities in different industrial and mobile applications.

An Overview of Lidar Imaging Systems for Autonomous Vehicles
TL;DR: In this article, the authors present an overview of the features of the light sources and photodetectors specific to lidar imaging systems most frequently used in practice and a brief section on pending issues for lidar development in autonomous vehicles has been included, in order to present some of the problems which still need to be solved before implementation may be considered as final.
