Efficiency and mode discrimination of a linear array of square CO/sub 2/ waveguide lasers phase-coupled by an intracavity spatial filter

In this paper, we present a theoretical analysis of a linear array of square waveguide CO/sub 2/ lasers phase-coupled with an intracavity spatial filter. Using a Rigrod-like method, we calculate the efficiency of the device and analyze its capability to discriminate between the fundamental mode and the transverse modes of both the array and the individual square waveguide.<
