A novel unstable resonator configuration with a self filtering aperture
Abstract
A novel unstable resonator configuration is described in which the field limiting aperture in a negative branch unstable resonator acts as a spatial filter to shape an almost gaussian beam and to cool the hot focal point inside the cavity down to non-damage limits.
