Yd. Liu et al., CHAOTIC AND PERIODIC PASSIVE Q-SWITCHING IN COUPLED CO2-LASERS WITH ASATURABLE ABSORBER, Physical review. A, 50(4), 1994, pp. 3464-3470
Two CO2 lasers With SF6 as an intracavity saturable absorber were opti
cally coupled, and their passive Q-switching dynamics were investigate
d. The amount of coupling used induced transitions from two unsynchron
ized periodic oscillating lasers into two synchronized chaotic ones. C
onversely, the uucoupled lasers set in the chaotic regime could be mad
e synchronized with a periodic pulsation after their coupling. Numeric
al solutions for the laser equations agree with the observations.
