Multiple light scattering and optomechanical forces [PDF]
, 2010 When off-resonant light travels through a transparent medium, light scattering is the primary optical process to occur. Multiple-particle events are relatively rare in optically dilute systems: scattering generally takes place at individual atomic or ...
