SUMMARY
The purpose of the air gap in gas lasers, specifically between the lasing gas and the partially silvered mirror, is to facilitate precise machining and polishing of the glass components. This air-filled space allows for the necessary optical quality of the mirror, which cannot be achieved at the bottom of a long, blown glass tube. By positioning the mirror away from the gas tube, manufacturers ensure optimal performance and light output from the laser.
