Research Investigation of Picosecond and YAG Laser Systems
Abstract
The report discusses the investigation of the frequency stability characteristic of single-frequency Nd:YAG 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 Nd:YAG 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.
