… In this paper, we prove that piston-type phase ambiguity will occur in coherent beam
combining (CBC) systems with a centrosymmetric distribution of sub-apertures. In some specific …

… that coherent combining … coherent combining algorithm, and uses improved DSP algorithms
for frequency estimation and carrier-phase estimation (CPE) that result in efficient coherent …

… The principle of distributed phase-locking is also illustrated. … lasers are coherently combined
by this method. The experimental results show that the structure can achieve phase-locking …

… such that the beams coherently combine at the receiver while … the coherent combining is
achieved immediately at the transmitter output. Therefore, in internal feedback, phase locking is …

… then combine the results so as to recover the reduced sideband signal strength. Coherent
combining is more gainful than the noncoherent … we want to coherently combine odd and even …

… when the phase lock point is … combining efficiency, as it is difficult to determine the right
beam to adjust. Our group proposed a method utilizing deep learning of the coherently combined …

… use of spectral coherence for estimating phase locking is due to the use of the particular
phase-… used the SSD approach in combination with HT to reconstruct the instantaneous phases. …

… The phase lock process has been automated with the creation of a reverse hill climbing
algorithm and the use of a microcontroller ATmega328P. Remarkable CBC efficiencies over 80 …

… decades and the mutual coherence between the two arms of … coherence between two
frequency combs has been to lock, … : for instance, combining an electro-optic phase modulator and …

… Phase locking of an array of lasers is a highly effective way to combine coherently the
output radiations from individual lasers to achieve beam shaping and a higher output power. …
