How matter responds to light lies at the core of vision, photosynthesis, solar cells and light-emitting diodes, and many other fields of scientific and practical import. But until now, it hasn’t been possible to see just how light does it. Berkeley Lab scientists have used SLAC’s Linac Coherent Light for the first demonstration that x-ray and optical wave mixing reveals not only structure but evolving charge states on the atomic scale.
Using a unique optical trapping system that provides ensembles of ultracold atoms, Berkeley Lab scientists have recorded the first direct observations of distinctly quantum optical effects - amplification and squeezing - in an optomechanical system. Their findings point the way toward low-power quantum optical devices and enhanced detection of gravitational waves among other possibilities.
