The Antares optical train is designed to eliminate stray, wide-angle optical paths through the network so as to avoid parasitic oscillation paths. ... Figure 5 is a schematic diagram showing all of the key alignment devices required to implement the alignment scheme into Antares. ... Both of these laser beams are spatially filtered and expanded by the beam-expander/ spatial-filter device, which is also ? partanbsp;...
