Claim 19:
20. The laser ranging system of claim 12, wherein:
the laser ranging system comprises a first beam splitter configured to split a combined pulse generated by the optical source into a plurality of separated pulses having different wavelength bands, the first pulse being among the plurality of separated pulses;
the laser ranging system is configured to separately modulate each of the plurality of separated pulses in response to a data transmission signal, thereby encoding transmission data into the plurality of separated pulses;
each of the plurality of separated pulses has a respective coherence length of less than 400 microns;
the laser ranging system comprises a second beam splitter configured to direct the plurality of separated pulses to a respective photoreceiver of a plurality of photoreceivers, the photoreceiver being among the plurality of photoreceivers;
each of the plurality of separated pulses comprises respective ray paths that arrive at the respective photoreceiver of the plurality of photoreceivers according to a respective temporal distribution curve; and
each of the plurality of separated pulses has a respective FWHM value of its temporal distribution curve that is at least three times as large as a respective coherence time value equal to the respective coherence length of the respective separated pulse divided by the speed of light through the variably refractive medium.
