Abstract
Laser resonators having nonuniform magnification can provide an advantage over constant magnification resonators in terms of energy extraction and far-field performance for low-gain lasers. This work explored the experimental characteristics of a resonator that was designed to have a lower magnification at the center of the resonator than at the edge. This was achieved using aspheric mirrors. Misalignment sensitivity, intracavity intensity, polarization, and collimation measurements were made. Results illustrate that some geometric properties were predictable and that aspheric mirrors can be used in resonator designs. In addition, the feasibility of using aspheric mirrors was evaluated. For certain applications, nonuniform magnification resonators using aspheric mirrors offer promising options.
