Abstract

The intensity of elastic scattered light from a single water droplet evitated by the 514.5-nm radiation of an argon-ion laser was recorded as the droplet was slowly evaporating. Abrupt changes in the scattered-light intensity were observed at the positions of morphology-dependent resonances with order numbers less than or equal to 3 and mode numbers between 129 and 165. The corresponding mode numbers and order numbers have been identified. Features attributable to the deformations of the droplet because of the sudden increase of the levitation force near the narrow morphology-dependent resonances were observed.

  31. The argon-ion laser was in multimode operation. The theoretical Q values of these fourth-order modes are ˜106 and thus are not high enough to resolve the laser modes.
