Numerical investigation of dynamic coherent beam combining in turbulent atmosphere with taking into account the double-pass delay

Numerical investigation of dynamic coherent beam combining of 7-channel laser radiation and its focusing on the remote target in turbulent medium has been carried out using the stochastic parallel gradient algorithm with the double-pass delay taken into account. Beam combining efficiency has been ex...

More Information
Summary:Numerical investigation of dynamic coherent beam combining of 7-channel laser radiation and its focusing on the remote target in turbulent medium has been carried out using the stochastic parallel gradient algorithm with the double-pass delay taken into account. Beam combining efficiency has been explored under various ratios between the phasing system frequency and Greenwood frequency.
