Abstract

We report on the development of a pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) laser operating at a 1116 nm wavelength. Because the third harmonic is within a few gigahertz of the 372 nm absorption line of iron, this laser system represents an alternative to alexandrite lasers commonly used in iron fluorescence lidars. With our prototype, we achieved a 0.5 W at 372 nm wavelength and a 100 Hz pulse repetition frequency. As a proof of concept, we show iron density measurements, which have been acquired using the novel lidar transmitter.
