Mystery of Optical Solitons Solved Using Atomic Terahertz-Vibrations

Stable packets of light waves – called optical solitons – are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation.

Using Light to Propel Micrometer-Sized Drones

A hand-held laser pointer produces no noticeable recoil forces when it is "fired" - even though it emits a directed stream of light particles. The reason for this is its very large mass compared to the very small recoil impulses that the light particles cause when leaving the laser pointer.
