Investigation of the coherent combination of a 19-fiber laser beam characteristics to achieve a multi tens of kW at a distance of 10 km
In this paper, we used a coherent beam combination to design a 50 kW high power laser beam for energy applications.Because of the strong environmental turbulence, degrade the coherent beam combination advantages, low turbulence level is considered.Combining elements are composed of 19 polarized single mode 3 kW high power fiber lasers where are arr
