As a result of the recent activities lidar in Colombia, it has been possible design and operation of an lidar station based on a pulsed Nd:YAG laser operating at the 1064-nm and 532 nm wavelengths. The objective of this project is to study aerosols optical properties in the Medellín atmosphere, (Longitude 75º 34 '05'' West, Latitude 6º 13' 55'' North), using an elastic backscattering LIDAR, and to derive quantitative information about its optical parameters of the tropical region. We report the work related with generation and conformation of pulses laser, couple to the emitter system, design and compact conformed of the optic and optoelectronic receiver and detector systems using APD and PMT´s with current-feedback amplifiers and features a very large gain-bandwidth product, as well as the synchronization and record of the backscatter signals lidar in Tektronix Oscilloscope.
