Solid-state diode pumped eye-safe lasers in remote sensing and ecological monitoring systems

摘要

The perspective of using diode pumped solid-state 1.5-2 μm lasers for synthesis of laser measurement systems is discussed. Comparative estimations of atmospheric transmission in spectral windows of 1.0 - 1.1μm, 1.5 - 1.7μm and 2.0-2.3μm are made, and characteristics of solid-state lasers and low-threshold receivers are considered. It is shown that lasers based on Yb-Er glass and crystals doped with erbium and holmium ions are preferable to lasers based on non-linear optical converters of neodymium-lasers radiation to the 1.5 - 2μm spectral region by their "efficiency/cost" ratio.
