State-of-the-art optics measurement, coating and finishing techniques were needed to withstand NIF s high-energy lasers, as were methods for amplifying the laser beams to the needed energy levels.
2.
They emphasize, in parallel with Einstein's theory of special relativity, that for the proper analysis of quantum optics measurements with different frames of detection, one must consult a conceptual map of events which takes into account the perspective of the observer implicitly.
