Mode-Resolved Measurements of the Linewidth Enhancement Factor of a Fabry–PÉrot Laser

Asier Villafranca, Asier Villafranca, G. Giuliani, Ignacio Garcés

Abstract

The linewidth enhancement factor of a multiple longitudinal-mode laser is measured using both the traditional Hakki-Paoli method and two proposed modifications to techniques that are generally used for single longitudinal-mode lasers. Parameters are measured separately for the different modes and compared.
