heal.abstract	A TEA-TEA HF (SF6:C3H8:He) oscillator-amplifier laser system with one common switching element and one common power supply unit was designed. Two different preionization schemes were employed, one using a corona discharge on a glass plate and another one using semiconductor slabs. For both arrangements the small signal gain coefficient go and the gain value G were determined and the dependence of g,, and G on the charging voltage and the active gas concentrations was investigated, Measurements of the performance characteristics of the HF laser oscillator (i.e. beam divergence, pulse energy, pulse duration, etc.) are presented and the improvement of the output laser beam profile is discussed in detail via 2D and 3D figures obtained with the help of a beam analyzer. The laser system presented is suitable as a research toot for a number of applications and among them some medical ones (microsurgery, dentistry etc.). (C) 2002 Elsevier Science B.V.
