Abstract: The intermode competition of orthogonally polarized modes in a broadband frequency modulated double-mode laser within a numerical model was investigated. The modulation is implemented by a corresponding change in the length of the resonator. Parameters of the active medium correspond to He–Ne lasers with an inhomogeneous broadened gain line. It is shown that negative effects of the competition can be significantly reduced at certain values of the modulation frequency and the frequency deviation.
