Abstract :
The author develops the theory and numerically analyzes the capability of a linear array of hollow dielectric square waveguide CO 2 lasers phase coupled by the Talbot effect. The author used a Rigrod-like analysis for computing the power supplied by the phased array versus the insertion losses induced by both the filling factor and the finite number of lasers. The result is compared to the one obtained with an identical device in incoherent mode. This makes it possible to define a coupling efficiency. An arrangement able to improve this coupling efficiency using a three-mirror cavity is presented
