The approach is to use foundational materials science, structural design, thermal analysis, optic fabrication, and space systems engineering, and to use optimize them through large-scale simulation to realize meter-scale telescopes at 10X cost reduction.  LLNL’s folded Gregorian design integrates all alignment sensitive components into one static monolithic system.  Like solid-…

A thyristor will stay conducting until the current through the device is zero (“current zero”) or perhaps slightly negative.  LLNL’s approach is to use the opticondistor (“OTV”) to force this current zero in order to force the device into an “off” state.  By combining a light-activated thyristor with an OTV, a noise-immune, high efficiency, high-power switching device can be…

The approach is to leverage the fact that a momentary “load” equal to the power transmission line impedance, (Z0), during the transient can suppress its propagation.  Z(0) is typically a fixed impedance of several hundred ohms based on the geometry of most single wire transmission lines.

So, an isolated self-powered opticondistor (OTV) system may provide an ultrafast method of…
