Experimental and numerical investigations were made of the stimulated emission regimes of two coupled CO2 lasers with different resonators. A difference between the resonator lengths amounting to λ /2 could give rise to two locking regions when a co

A study was made of the influence of misalignment of the plane mirrors of a waveguide CO2 laser on the output power and mode structure of the radiation. It was found that misalignment of the resonator only weakly affected the output power, but exerte
