Abstract

From experimental results we characterize the catastrophic damage threshold of mirrors irradiated with cw CO₂ laser by a critical temperature. Analytical expressions of the mirror temperature versus beam radius are developed. A comparison between experiments and theory shows that P/R determined in test is the good ratio to compare mirror coatings and to scale test.
