All-solid-state, narrowband, pulsed sodium D2 resonance light source

摘要

We are working on a sodium lidar project at the European Incoherent Scatter (EISCAT) association (69.6°N, 19.2°E) near Tromsø, Norway. Sodium lidar requires a pulsed narrowband sodium resonance light source [1]. Such a source based on nonlinear frequency mixing of all-solid-state lasers has several advantages over the more commonly used dye lasers [2]. However, it has not been put to practical use for sodium lidar.
