In many lighting applications, measuring the relative intensity of two light sources is more important than measuring their individual intensity. This ensures that two light sources shine with the ...

Researchers have demonstrated a record-high laser pulse intensity of over 10 to the exponent 23 W/cm2 using a petawatt laser. It took more than a decade to reach this laser intensity. These ultrahigh ...

Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but ...

A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.

Some neurological disorders can be improved through photobiomodulation, a non-invasive technique based on the application of low-intensity light to stimulate altered functions in specific regions of ...
