TL;DR: In this paper, the authors reported coherent combining of a record 48 PM fibres in a phased array configuration, and the resulting Strehl ratio degrades by 1000 fibres, achieving the state-of-the-art performance.

TL;DR: In this paper, the authors demonstrate successful beam control of a fiber optic phased array containing a large number of polarization maintaining fibers using individual all-fiber phase modulators with a residual phase error less than 1/30th of a wave.

TL;DR: A cryogenic Yb amplifier using two laser materials, Gd3Sc2Al3O12 and Y3Al5O12 (YAG), has been used to obtain 70 W average power at 5 kHz pulse repetition frequency and the gain broadening obtained by combining two media enables shorter pulses than using Yb:YAG alone but retains the power-scaling advantages of cryogenic SOTA.

TL;DR: In this article, the authors report coherent combining of thirty-two PM fibers with a 2D fiber array as the beamformer, achieving a phase error of ≪λ/50.

TL;DR: This work presents an approach for constructing equations describing the effects of atmospheric turbulence on propagating light based on equations and concepts that will be familiar to those with a background in paraxial wave-optics modeling.
