This work describes the design and testing of a highly-tunable differential absorption lidar (DIAL) instrument utilizing an all-semiconductor transmitter. This new DIAL instrument transmitter has a highly-tunable external cavity diode laser (ECDL) as a seed laser source for two cascaded commercial tapered amplifiers. The transmitter has the capability of tuning over a range of ~ 17 nm centered at about 832 nm to selectively probe several water vapor absorption lines. This capability has been requested in other recent DIAL experiments for wavelengths near 830 nm. The transmitter produces pulse energies of approximately 0.25 µJ at a repetition rate of 20 kHz. The linewidth is exceptionally narrow at |
