Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a ...

At the core of the breakthrough is an optical parametric oscillator (OPO), a resonator that converts incoming laser light into new frequencies using a nonlinear crystal. For decades, OPOs have been ...

Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillon years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise ...
