Chinese researchers have reportedly demonstrated a new way to dramatically enhance ultrafast laser interactions without increasing overall laser power. Their findings could potentially open the door to safer and more precise high-intensity optical systems.
In a study published in Nature, researchers led by Jian Wu at East China Normal University made the discovery using a form of quantum light known as bright squeezed vacuum.
Using this, they boosted a key nonlinear optical process by more than 20 times compared to a conventional laser pulse carrying the same average energy.
According to the team, their work tackles one of the biggest limitations in modern laser physics.
