Abstract

This work reports on the design, construction and commissioning of a ultraviolet scanning Raman lidar system, which is deployed at the Otlica observatory in Slovenia. The system uses a fast parabolic mirror as a receiver and a frequency-tripled Q-Switched Nd:YAG pulsed laser as a transmitter, both are mounted on a common frame with steerable elevation angle. Custom optics using a low f-number aspheric lens were designed to focus the light into a UV-enhanced optical ber, used to transfer the lidar return signal from the telescope to the polychromator. Vibrational Raman spectra of N₂ and H₂O were separated using narrow-band interference lters combined with dichroic beam splitters. System functionality and performance was assessed in a series of preliminary experiments and by the comparison of the retrieved results to radiosonde data.
