Although this transparent crystal closely resembles ordinary window glass, it exhibits extraordinary ... further exploration in extreme-condition optical systems," said OU Physics Professor ...

For this purpose, this new ion crystal clock was compared with other optical clocks and a new accuracy record was achieved. The PTB researchers report their in Physical Review Letters. An undisturbed ...

The cavity contains a nonlinear optical crystal, which can be used to generate squeezed states of light. The squeezed light is coupled to the cavity modes and can enable strong interactions with the ...

It determines the strength of the nonlinear effects and is related to the crystal's symmetry and electronic structure. Materials with high nonlinear susceptibilities are desirable for efficient ...
