【Abstract】 The chaotic dynamic of a loss-modulated Nd∶YAG laser was researched at first.And then,a sinusoidal signal was injected into the bias voltage of the laser,which can control the laser to achieve the different periodic orbits by adjusting the amplitude of the sinusoidal signal.Not only the output power of the laser was enhanced but also the good laser was obtained by using this control scheme.Finally,simulation results show the validity of this control method.The control scheme is easy to realize in engineering.Our research results have many helpful values to improve the laser output power.更多还原
