Скачать или смотреть Optical Tweezers Can Control Electrical Charge: New Breakthrough Explained

Scientists have achieved precise control of electrical charge on objects trapped in optical tweezers, reviving a phenomenon first observed by Nobel laureate Arthur Ashkin in the 1970s.
In this video, we explore how an international team led by Scott Waitukaitis at the Institute of Science and Technology Austria rediscovered and refined Ashkin's charging effect. Learn how laser beams can manipulate electrical charge through two-photon absorption and why this breakthrough matters for atmospheric physics research.
Key Topics Covered:
What are optical tweezers and how do they work
Arthur Ashkin's Nobel Prize-winning invention
How laser light charges trapped particles
Two-photon absorption process explained
