Paper 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 improvement of the laser beam characteristics of the TEA HF laser oscillator, such as beam profile and output energy, was investigated. The beam profile is discussed and presented in detail in 2D and 3D figures with the help of a beam analyzer system and the gain measurements for the specific active gas mixture and the specific laser head geometry are given in terms of the small signal gain coefficient go and the gain value G parameters.
