Semiconductor laser and diode-pumped solid state laser techniques are reviewed concerningremote sensing and precision instrumentation. First, the basic principles of remote range detectionusing these lasers are compared for a pulse method, intensity modulation method, randommodulation method, and frequency modulated (FM) heterodyne method. These methods are appliedto lidar (laser radar) for detecting the spatial distributions of atmospheric aerosolparticles. The FM heterodyne method is-capable of accurate measurement of both absolute rangeand displacement when widely tunable diode lasers are used. As potential applications ofdiode-pumped solid state lasers, a coherent lidar and a space lidar as well as an interferometerantenna of gravitational waves are introduced.
