Ii. Zolotoverkh et al., INFLUENCE OF PERIODIC LOSS MODULATION ON THE DYNAMICS OF SELF-MODULATION OSCILLATIONS IN A SOLID-STATE RING LASER, Kvantovaa elektronika, 23(7), 1996, pp. 625-629
A theoretical investigation is made of the influence of periodic modul
ation of intracavity losses on the dynamics of a solid-state ring lase
r operating in a type I self-modulation regime. Analytic solutions are
obtained for describing dynamic periodic locking of the frequency ome
ga(m) of self-modulation oscillations to the frequency omega(p) of per
iodic loss modulation and a quasi-periodic regime characterised by low
-frequency modulation of self-modulation oscillations at the differenc
e frequency omega(m) - omega(p). Analytic expressions are obtained for
the width of the region in which locking of the frequency of self-mod
ulation oscillations takes place. Numerical simulation of the dynamics
of a solid-state ring laser is used to study the transition of this l
aser to dynamic chaos when the loss modulation depth h is increased. I
t is shown that the operational regimes of the laser and the condition
s for its transition to dynamic chaos are significantly different in t
he frequency ranges omega(m) > omega(p) and omega(m) < omega(p). The b
oundaries separating regimes with chaotic, periodic, and quasiperiodic
dynamics are found in the (omega(p), h) plane.
