Stimulated emission of collective modes in two optically coupled lasers was investigated experimentally and numerically. A mathematical model was used to describe both single-frequency and two-frequency lasing regimes of the coupled system and a good

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

Measurements were made of the phase difference between the output beams of two coupled CO2 lasers operating in a coherent regime. The results of the experiments are in qualitative agreement with calculations performed on the basis of a point model of
