Abstract

Coherent ladar detection which is virtually free of oscillator instabilities (random phasing effects) may be obtained through the use of two local oscillator frequencies and subsequent four-wave mixing for heterodyne square-law detection. Such a stabilized four-wave system will allow for more compact, lighter, simpler, and shorter-wavelength coherent ladars.
