Abstract
Each mode inside a rectangular slab-waveguide laser consists of four quasi plane waves propagating at small angles to its axis and inducing specific grating ofthe refractive index in the slab medium. Multimode operation of such laser is a superposition of single modes. Each mode can be spatially separated into two high quality lobes with M2 parameter near l . When geometry ofthe slab is controlled, high stability of a mode pattern can be obtained. This effect is particularly strong when extra single mode selection (for example Talbot filtering) is applied. The experimental evidences were performed on a RF excited CO2 slab-waveguide laser.
