Construction and characterization of a CO2 wave guide laser with a special electrode design for materials processing
(2001-01-01)
We describe the design and construction of an efficient tunable CO2 wave guide laser which was used for thermal graving of predigitalized images over polymeric materials. The small internal diameter of the cylindrical wave ...
Infrared and far-infrared spectroscopy of (CH3OH)-C-13: TeraHertz laser lines and assignments
(Elsevier B.V., 2007-02-01)
We use a (CO2)-C-13 laser as optical pumping source to search for new THz laser lines generated from (CH3OH)-C-13. Nineteen new THz laser lines (also identified as far-infrared, FIR) ranging from 42.3 mu m (7.1 THz) to ...

Influence of magnification on extraction efficiency in laser resonators with non-overlapping beams
(Institute of Physics Publishing, 2015-04)
The magnification and the Fresnel number determine the mode profile and losses in a bare unstable resonator. Upon inclusion of gain, both the beam pattern and the reflectivity are changed, more than in a stable cavity, ...
