Abstract :
Summary form only given. We present a single-longitudinal-mode external-cavity diode laser developed as a tunable laser source for an airborne water vapor differential absorption lidar (DIAL) system. The small efficient laser is ideal for airborne and space-based applications where size, weight, and power consumption is a concern. This system is designed to operate in the 935-nm band, in which the absorption cross sections are /spl sim/20 times stronger than the absorption bands at 720 and 820 nm.
