7 Advantages of Slab-Technology Compact Excellent mode structure (K-factor 0.8 or better) Low service requirements/low cost of ownership No moving parts Uncoated copper resonator optics Diamond window as the only transmissive optic No gas installation Very low gas consumption (gas bottle change: once a year) Low weight, laser head can be moved Potential for eliminating the external beam telescope 5/ RSL - 7

8 Diffusion-cooled CO 2 Slab laser Components Control system 4 Beam output Resonator housing Internal gas supply 5/ RSL - 8

9 Advantages of diffusion-cooled CO 2 Slab Lasers very compact and nearly wear-free construction high beam quality (K-Faktor > 0,8) no gas heat exchanger required low optical loss very high thermal stability low gas consumption, no external gas cylinders necessary no gas flow and therefore no contamination of the resonator optics low maintenance 5/ RSL - 9
