Ashkin: acceleration and trapping of particles by radiation pressure

What changed

Observed laser-driven acceleration and trapping of dielectric particles.

Scientific scope

The record is Ashkin's sole-author 1970 Physical Review Letters paper. It does not absorb later single-beam gradient traps, atomic laser cooling, biological optical tweezers or the paper's proposed extensions to atoms and molecules as completed demonstrations.
