【摘要】 为了达到实际应用所需的半导体激光器的输出强度,我们首先通过调制电流的方式将1.55μm半导体激光系统混沌化,然后利用参数自适应方法实现了混沌控制,来获得所需的激光输出强度。这种混合控制策略是其他方法无法比拟,不仅能将激光系统稳定控制到系统的平衡点上,而且能根据不同的控制目标选择不同的控制强度,在控制范围内都能很快地获得所需的稳定的输出激光。该研究的思想、方法和结果对改善实际激光系统稳态输出的快速性、输出功率的灵活可调性和能量转换效率都具有理论意义和实际参考价值。更多还原

【Abstract】 n this paper, a semiconductor laser with 1.55μm is chaotifled by adjusting its current at first. Then, the parameter adaptive control strategy is used to control the chaos in this laser system .The advantage of anti-control and control of chaos strategy is that the desired stable output laser can be obtained in a short time and the output power strength of the laser can be adjusted flexibly in accordance with the engineering requirements. Theory analysis and simulation results show that the control method results in the powerful stability and robust. Our research results have very helpful values to improve the speed of stable output, flexible adjustment of laser output power as well as efficiency of energy transformation for real laser system.更多还原
