Paper Abstract

An infrared aerosol lidar has been developed which operates at the eyesafe wavelengths 1.54 or 1.56 micron, generated by a Nd:YAG laser and stimulated Raman scattering. The pulse energy is greater than 30 mJ at 10 Hz repetition rate. The backscattered radiation is collected by a 38 cm F/5 Newtonian telescope with a f = 9 mm, 84-deg field-of-view eyepiece, and detected by a cooled germanium detector. Signal digitizing is done by a 12-bit 10-MHz transient recorder and a PC 386. After assembling of the system Raman-shifting experiments were carried out to optimize the output in the eyesafe wavelength. First backscatter profiles are expected to be available at the conference.
