Abstract

Low-temperature suppression of nonlinear losses leads to improvement in nanosecond lasing threshold of self-assembled oligophenyl nanofibers by two orders of magnitude. Laser dynamics is revealed by time-resolved photoluminescence excited by femtosecond and nanosecond pulses. Strategies are discussed to extend low-threshold operation of nanofiber lasers to room temperature.
