Abstract
We have observed and explained the asymmetry in the power profile of a line-tunable single longitudinal mode (SLM) CW CO2 laser. A positive feedback effect due to heating of the intracavity optical components in the presence of laser beam is the cause of the asymmetry and the hysteresis in the power profile. We have shown that due to this effect, off-line-centre tuning on the higher frequency side of the power profile is almost impossible when zinc selenide Brewster windows are used.
