“D-Modulation” Results in Anti-Controlling-Chaos of A NH3 Laser

By performing on mutations and period-stimulations of the frequency detuning of the molecule vibration frequency of laser gas and laser oscillation frequency, this paper carries out our studies of anti-controlling-chaos of a NH3 laser. We present a laser physics model of the anti-controlling-chaos of NH3 laser. By performing on a mutation of the frequency detuning, we achieve successfully the anti-controlling-chaos of NH3 laser, and which results in a stable state of NH3 laser being anti-controlled to become of chaos, beating, and quasi-period. By performing on a period-stimulation of the frequency detuning, the anti-controlling-chaos of NH3 laser is also achieved successfully, and which also results in chaos, period-three, period-ten, and other quasi-period appearing. Our work shows an important value to study laser systems, chaos-control, chaotic laser emitters, nonlinear optic devices, and control science.
