Thermooptical processes in the window of a high-power gas laser

Аннотация

We have developed a mathematical model of thermomechanical and thermooptical processes that proceed in the output window of a continuous gas laser of a multikilowatt power. Optimal parameters have been determined at which the output window not only successfully withstands an extreme radiation load, but also ensures the radiation coupling with a minimum possible divergence. We have used numerical modeling to analyze the properties of the most promising materials used in high-power СО₂, СО, and oxygen–iodine lasers.
