A compact gas single-mode radio-frequency excited laser with a hybrid unstable and waveguide cavity
- Pedagogical Univ., Ryazan (Russian Federation)
In recent years we have seen a steady increase in the use of transverse radio-frequency (RF) gas discharges for excitation of carbon dioxide (CO{sub 2}) lasers. However, RF excitation can be realized in carbon oxide (CO) and xenon (Xe) lasers. We attempt to construct a RF laser, which can work in broad spectral range of radiation. The design of this laser is based on the use of unstable telescopic cavity with the radiation spreading both in the free space and inside the waveguide. Employed discharge structure is formed by two parallel identical electrodes 30 x 230 mm in area and allocated at 2.5 mm distance from one another, and it has a gap, which is not confined limited by side walls. This ensures convective gas exchange between the reserve and active zones. This construction allows to get a high output power of generation with lasers having small dimensions, provides an opportunity to use single-mode generation for the basic hybrid mode; the latter is a combination of the lowest mode of gap waveguide and the lowest mode of unstable cavity.
