Laser activity. Present capabilities for generating a LIDAR optical frequency by means of a ND-YAG laser

The choices arise from the possible utilization from the fundamental wave, of the Nd-Yag Laser, or its harmonics with dyes and crystals. Crystals such as KDP and ADP were used for second harmonic generation or sum frequency generation. A crystallographic solution was calculated for type I and type II phase matching process with temperatures between each crystal Curie point and 393 K. The principal Lidar missions were studied: atmospheric density, aerosols, temperature, O3, OH, ClO, NO2, SO2, H2O, Na, K, Mg, Mg(+), and MgO.
