摘要

The progress in the development of a prototype High Spectral Resolution Lidar (HSRL) and the associatedsub-systems for atmospheric monitoring in Ultra High Energy Cosmic Ray Observatories, will be presented in this work.In this frame, a conceptual design of a pulsed, narrow linewidth and frequency stabilized laser operating in near UV andproviding multi-wavelength light beam is also described. From experimental point of view, we developed and tested theappropriate methods to characterize a commercial CW SLM Nd:YVO4 laser at 532 nm with respect of its single modeoperation performance and frequency stability. Additionally, we describe the methodology and the associated resultsconcerning the optical characterization of a candidate FabryPerot etalon being used as spectral discriminator for themolecular channel of the HSRL. For this purpose a commercial FabryPerot etalon was used as a reference to verify ourresults. The details of the method for accurate measurement of the effective spacing, the parallelism and the flatness ofthe etalons are also presented.
