Abstract

In laser isotope separation experiments a high-speed IR recording camera ITMGT has been used. With the help of this camera we were first to realize photographic recording of the spatiotemporal radiation structure in the chemical reactor located inside the resonator of a high-power CO₂ laser. The obtained photographs reveal spatial nonuniformity of the radiation structure and self-focusing of laser radiation inside the resonator. Owing to the obtained information it has become possible to study the physics of self-focusing initiation in media with nonlinear absorption of IR radiation and this information will be useful for optimization of the processes of isotope enrichment by CO₂ laser radiation.
