“…A different approach for deriving an axial discharge uniformity was achieved by coupling a waveguide antenna to a microwave stripline, thus enabling the propagation of a TEM mode [7]. A helical excitation of a cylindrical laser was suggested as well [8,9]. All these devices [1][2][3][4][5][6][7][8][9][10] do not employ the advantageous features of the slab configuration, and require a large overhead for gas cooling and circulation.…”

A new microwave‐excited CO2 slab‐laser scheme is demonstrated in a slow gas‐flow laser experiment. The gas‐discharge axial homogeneity is improved by an H‐plane coupling of a rectangular resonator operating in the fundamental mode to a shorter slab laser‐head resonator, below the cutoff. This paper describes the conceptual experimental and practical aspects of the microwave‐excited laser. © 2002 Wiley Periodicals, Inc.
