The cw, interpulse, and intrapulse frequency stabilities of a compact, sealed-off CO2 Doppler lidar transmitter are characterized. A cw stability of 1 part in 5 × 1011 for 1-s averaging times, maximum pulse-to-pulse frequency deviations of ±49 kHz for periods of seconds at a pulse repetition frequency of 1 kHz, and pulses with low-frequency chirp are demonstrated in a instrument suitable for the field.
