ABSTRACT:
The power output of a gas laser is maximized by (1) suppressing high order transverse modes, (2) broadening the gain curve to increase the number of axial modes that can lase in a given length of cavity and to thereby reduce power variation due to longitudinal mode sweeping resulting from thermal effects on cavity length, (3) suppressing unwanted infrared lasing activity, and (4) reducing beating noise resulting from frequency offset due to dispersion.
