Abstract
Taking advantage of the wide bandwidth possible with inductive excitation at audio‐frequencies, square‐wave excitation at 2.5 kHz has been employed to obtain laser oscillation of the 4880‐Å ArII transition in a high numerical aperture active medium 1 cm in diam and 15 cm long, without the aid of an axial magnetic field.Keywords
