Paper Abstract

This paper reviews and discusses the performance of unstable resonators concentrating on the design, analysis, and test of oscillators used on electric discharge laser devices. The work covers over 15 years of pulsed CO2 laser device development. The emphasis is on the review of the energy extraction and beam quality experimental results from a wide range of devices. The effect of flow characteristics on laser performance is discussed. The interaction between the optical mode formation and the laser medium, called the 'Mode-Medium Interaction,' is presented. The device design constraints imposed by optical material limitations is also discussed.
