Abstract
In this paper, we have calculated the beam quality of practical unstable resonators under a variety of practical conditions. The effects of resonator geometrical parameters and misalignment were evaluated. Based on the Fresnel-Kirchhoff integral, the two-dimension phase and intensity have been calculated for practical positive branch unstable resonators. Using Second Order Moment (SOM) technique, Μ2 factor for such resonator was estimated. The results show that the beam quality is very sensitive to misalignment of the resonator. We also show that Μ2 factor increases with Fresnell number, while it decreases with magnification.
