Abstract
Near-infrared semiconductor diode lasers are useful for spectroscopic monitoring of a number of chemical species at parts-per-million levels and below. Although these devices are typically used in point sensing geometries, they can also be used in several remote sensing configurations. In this paper we discuss some of the properties of these lasers that are relevant for point detection, and we discuss a simple scheme to measure temperature and pressure. In the context of remote sensing, we discuss several modulation methods that allow for range- resolved detection of chemicals and aerosols using continuous wave diode lasers.
