Paper Abstract

We report the first demonstration of mid-IR coherent laser radar operation near 3.6 micrometers . In many low altitude environments, the wavelength region from 3.5 - 4 micrometers has advantages for laser beam propagation because the detrimental effects of scattering and turbulence are less severe than at shorter wavelengths. In addition, under conditions of high humidity, water vapor absorption in the mid-IR is also significantly lower compared to the long-IR region at 9-11 micrometers . The source in this work is a 100 mW, frequency stable cw-optical parametric oscillator (OPO) based on periodically poled lithium niobate. The frequency stability of the source is discussed and laboratory heterodyne experiments measuring small Doppler shifts from vibrating targets are described.
