  • Publication number: 20220026577
    Abstract: A dispersion gating-based atmospheric composition measurement laser radar. The atmospheric composition measurement laser radar stretches a femtosecond laser into a broad pulse laser in a time domain by means of dispersion. A femtosecond spectrum is mapped into the broadened laser pulse due to the group velocity dispersion, and then is subjected to time domain gating by means of an intensity modulator (22, 26) for completing the selection of a laser of a preset wavelength. The laser wavelength scanning is achieved by adjusting the delay of an electrical drive signal of the intensity modulator (22, 26). An absorption spectrum of a specific atmospheric composition is obtained by means of laser wavelength scanning so as to measure the concentration of the atmospheric gas composition. The atmospheric composition measurement laser radar can precisely perform free gating on the wavelength where the laser emits, and has high precision in selecting the wavelength.
