Appreciable enhancement in output and power efficiency for compact Ar II lasers (488.0 nm) is obtained by applying a transverse magnetic flux density at approximately 700 G. The enhancement factor amounts to as large as 3 in laser output and the efficiency becomes more than twice as much as without magnetic flux. A sharp rise in output occurs above the critical magnetic flux density, 450 G in the present work, where the cyclotron radius of electrons is nearly equal to one-half of the tube radius.
