Copper vapor laser lidar for tropospheric ozone sounding

For tropospheric ozone sounding with use of the differential absorption method a lidar is proposed operating at the nonconventional wavelength pairs: 271/289 nm (sum frequency of yellow and green radiation lines of copper vapor laser and second harmonic of copper vapor laser, yellow line, respectively) and 289/308 nm (308 nm is the excimer XeCl laser radiation wavelength).
