CO_2 Slab Laser with a Variable Reflectivity Grating (VRG) as Lineselective Element

摘要

A lineselective CO_2-laser with a 'Variable Reflectivity Grating' (VRG) instead of a 'Variable Reflectivity Mirror' (VRM) was realised. The binary grating has a constant grating-period and -depth and a modulated width of the grating-bars. Stable and unstable resonator designs were investigated.
