DEPENDENCE OF THE SELF-MODULATION FREQUENCY ON THE PARAMETERS OF A SOLID-STATE RING LASER

Theoretical and experimental investigations were made of the influence of the detuning of the lasing frequency from the centre of the gain l ine on the modulation frequency omega(m) in a type-1 self-modulation r egime when the cavity is characterised by amplitude and frequency nonr eciprocities, The moduli and phases of the coupling coefficients of co unterpropagating waves are arbitrary, It is shown that the amplitude n onreciprocity of the cavity has a strong influence on the nature of th e dependence of omega(m) on the frequency detuning. A comparison with the experimental results makes it possible to estimate the difference between the phases of the coupling coefficients of a ring Nd:YAG chip laser.
