A radiation source based on a solid-state Raman laser for diagnosing tropospheric ozone

A radiation source has been created on the basis of a solid-state Raman laser with an unstable telescopic cavity excited by the second-harmonic radiation of a Nd:YAG laser. Output radiation with a wavelength of 563 nm, an energy per pulse of up to 34 mJ, and a divergence of 2.4 mrad has been obtained with a pulse width of 12 ns. Doubling the radiation frequency of the Raman laser made it possible to obtain radiation at a wavelength of 281 nm (the energy in this case equals 4.2 mJ, the pulse width is 11 ns, and the divergence is 1.3 mrad), which can be used to diagnose ozone in the troposphere.
