Abstract

We report a new method for the measurement of the absorption coefficient of CO₂ laser windows. The method exploits the hysteresis in the power-tuning curve of a single-mode continuous-wave CO₂ laser and allows measurements of absorption coefficients of the order of ∼10^-3 cm^-1 in CO₂ laser windows a few millimeters thick.
