Solutions in a Crystal: New Light Source Could Serve in Geo-Navigation, Search for Earth-Like Planets
“Solution water waves can travel several kilometers without any significant change in their shape or amplitude, as opposed to normal waves, which widen as they travel, and eventually disappear. Discovered over 150 years ago in water canals, solutions represent a surprising phenomenon of wave propagation and have been observed in natural phenomena including moving sand dunes and space plasmas.”
The optical resonators are crystals shaped to form a resonator that can guide a solution light pulse on an endless circular path. When such a solution light pulse circulates inside the resonator, a small fraction of it can be extracted every time the pulse completes one round trip.
