TRANSIENT-RESPONSE OF A THRESHOLDLESS MICRODROPLET DYE-LASER

Abstract

Lasing in a cavity formed by a dye-doped micrometer-sized liquid droplet showed a new thresholdless steady-state behavior and a time-dependent response. The thresholdless behavior is associated with enhancement and inhibition of the spontaneous emission. The time-dependent response is related to various quality factors of the cavity modes and was determined to be 8 x 10(8).
