Unstable resonator optics are available to provide low divergence for applications requiring long distance propagation of the beam or the highest focussability.
A significant improvement to spatial coherence is also obtained, which is beneficial in some applications involving the use of diffractive optics (e.g. FBG writing, DOE hole drilling).
The beam is flat topped in both axes, with no occlusions, for divergence of <300 microradians
