Nd:GGG disk laser with coherent beam combining in Talbot laser cavity at multi beam diode pumping

摘要

The use of thin disk active elements leads to essential decrease in negative influence of the thermal distortions on the output parameters of solid-state lasers. We may increase the output power from the single disk without suffering from thermal distortion while using the multi beam pumping. The purpose of our work was the realization of phase synchronization of several laser channels with a cavity utilizing Talbot effect.
