Variable xy-UV beam expander for high-power laser
... In Table 5b we see the variable x-beam expander needs to cover the magnification range magxBE from 3.476 to 14.865, which is wider than the y-beam expander needs to cover (a ~4.3x optical zoom). We also see that, as with the y-beam expander, the largest w0R in combined with the furthest out z0 yield ...
