An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Recently, laser scientists at the Center for Relativistic Laser Science (CoReLS) within the Institute for Basic Science (IBS) in South Korea realized the unprecedented laser intensity of 1023 W/cm2.

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 ...

A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser.

Scientists in South Korea have achieved a major milestone in physics – and one pursued by researchers in the field for decades – by generating a record-breaking ultra-high intensity laser. The pulse ...

U.S. scientists have created their own "black hole" using the world's most powerful X-ray laser. Researchers in the past had used a lower-intensity beam on small molecules, which in turn stripped away ...

High-intensity laser therapy (HILT) combined with wound dressing was superior to conventional wound care, according to a recent study. High-intensity laser therapy (HILT) is a promising treatment for ...

WASHINGTON -- Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic ...
