Phase locking of a seven-channel continuous wave fibre laser system by a stochastic parallel gradient algorithm

A seven-channel fibre laser system operated by the master oscillator - multichannel power amplifier scheme is the phase locked using a stochastic parallel gradient algorithm. The phase modulators on lithium niobate crystals are controlled by a multichannel electronic unit with the microcontroller pr...

Zusammenfassung:A seven-channel fibre laser system operated by the master oscillator - multichannel power amplifier scheme is the phase locked using a stochastic parallel gradient algorithm. The phase modulators on lithium niobate crystals are controlled by a multichannel electronic unit with the microcontroller processing signals in real time. The dynamic phase locking of the laser system with the bandwidth of is demonstrated, the time of phasing is .
