Experimental study of gain-guided waveguide-array (1*10) CO/sub 2/ laser

A new type of waveguide-array CO/sub 2/ laser excited by an RF discharge is reported. In this device, laser beams are guided by means of periodic gain regions distributed in lateral space and form a one-dimensional array. Experiments indicate that the 1*10 array laser is perfectly locked in phase. In the far field, both symmetrical and antisymmetrical field distributions have been observed.<
