Abstract
Abstract A GAS LASER IN WHICH THE RESONATOR REFLECTORS ARE SUPPORTED BY AN ESSENTIALLY NON-ADJUSTABLE STRUCTURE IN A POSITION WHICH ESTABLISHES A FIXED AXIS FOR THE PROPAGATION OF RADIATION IN THE RESONATOR. MEANS ARE PROVIDED FOR INDEPENDENTLY ADJUSTING THE POSITION OF TWO LENGTH-WISE SPACED-APART PORTIONS OF THE PLASMA TUBE SO THAT THE AXIS OF THE PLASMA TUBE CAN BE ALIGNED WITH THE RESONATOR AXIS TO WITHIN A DISTANCE WHICH IS LESS THAN THE MODE DIAMETER OF THE RESONATOR RADIATION.
