Design and analysis of solar blind ultraviolet water vapor Raman lidar spectroscopy system
A spectroscopic filter system for solar blind ultraviolet water vapor Raman lidar, based on a hyperspectral grating, is designed and built. The system separates the vibrational Raman scattering signals of N<sub>2</sub> and H<sub>2</sub>O at central wavelengths of 283.6nm and 294.6nm efficiently and precisely, using the fourth harmonic output 266.0nm of the Nd: YAG pulsed laser as the excitation wavelength. The performance analysis of the grating spectroscopic filter shows that it has the rejection ratio to elastic scattering signal more than 5 orders of magnitude. The ZEMAX simulation and experimental data demonstrate that the spectroscopic system can realize high-efficiency extraction of weak solar-blind ultraviolet vibration Raman scattering signals with narrow spectral intervals, which verify the feasibility and reliability of the grating spectroscopic system.
