Abstract
All metal, non-free space, square-bore, RF-excited CO2 lasers [1] have 10-15% electro-optical efficiency and power extraction of up to 0.5 W/cm, which potentially could be further optimized In this presentation we describe an improved RF-excitation geometry, referred to as all-electrode bounded laser bore, schematically shown in Figure 1. This new electrode geometry helps to increase both the power extraction and efficiency of the diffusion-cooled RF excited CO2 laser.
