Our ESA Space-Optics project has reached a major milestone: We have finished the development of a novel beam collimation technique, which works allows us to adjust the waist of the laser beam emitted from a fibre coupler to an arbitrary position simply by maximising the peak intensity of the laser beam at some other position.
This is a fiber collimator manufactured from the ultra-low expansion material ZERODUR.
In order to make the coupler space-compatible it is manufactured from ultra-low-expansion ceramics (ZERODUR) and has no moving parts.
