Abstract

In order to improve the output beam quality of slab waveguide CO₂ lasers, we presented an optical phase-shifting array resonator with a phase-shifting array end mirror used in RF- excited diffusively cooled slab waveguide CO₂ lasers. A series of phase-shifting array end mirrors with different parameters are employed in our experiments and highly spatially suppressed single-peak intensity distributions in the far field, which have advantages of high brightness and good characteristics of propagation, have been obtained respectively. Theoretically we analyzed the characteristics of the output mode and well explained the phase coupling of this kind of slab waveguide CO₂ lasers.
