A Pulsed Solid-State Coherent Lidar for Naval Wind Sounding Applications

A pulsed coherent 2 lim diode-pumped solid-state lidar has excellent capability of meeting Navy requirements for remotely measuring atmospheric wind fields. The proposed 2 #m diode-pumped coherent lidar will be capable of pulse energies of -20 mJ/pulse and a PRF of >100 Hz, with a pulse duration of 200 us. Coherent Technologies, Inc. has developed the first 1.06 and 2.09 ,im flashlamp-pumped Coherent lidars. A 5 mJ/pulse diode-pumped 2.02 Vm transmitter has also been demonstrated. For this effort, a coherent lidar computer sLmulation will be utilized in optimizing systems performance and in determining design parameters. As existing 2 Vm coherent lidar system will also be utilized to experimentally confirm many critical design parameters. An overall design will be established using the results of the simulatioTi and field test efforts. Operational issues will be emphasized in the study effort. Component technologies will be reviewed in detail in the development of a plan leading to operational
