There is considerable interest in the subcentimeter laser ranging to ground targets and satellites. To determine atmospheric dispersion, the time interval between the received signals at different wavelengths has to be determined within 1–3 ps (Ref. 1) depending on the pair of wavelengths chosen in a particular experiment. We have reported several experiments to optimize the color pair with respect to existing high power solid state lasers and photodetectors (0.53/0.35,2 0.53/ 0.68,3 1.06/0.53 μm4).
