The report discusses the investigation of the frequency stability characteristic of single-frequency NdYAG lasers, and of the use of coherent ultrashort pulses for high resolution imaging. Technical Results on the first topic include the locking of a single-frequency NdYAG laser to the bandpass of a high finesse Fabry-Perot interferometer the use of etalon thermal tuning of the laser for course frequency control the construction of a second single- frequency laser and the heterodyning of the two single-frequency YAG lasers at a variable frequency offset. In the area of high resolution imaging, a discussion of the application of microwave synthetic aperture techniques to optical radar is presented as are initial results of an experiment to obtain high optical resolution by doppler processing.
