| 摘 要： | 为提高宽谱光纤光源温度稳定性,对平均波长温度稳定性进行了分析;对不同泵浦功率下输出光的平均波长与输出功率的变化进行了仿真和实验研究,揭示了宽谱光纤光源平均波长与输出功率的相关性;提出并实现了一种基于数学模型的平均波长控制技术.从光源输出取出小部分功率作为反馈信号,通过调整泵浦激光器电流实现了中心波长的精确控制.对研制的样机进行了实际测试,结果表明控制方案是可行的,在－45~70℃的温度范围内,宽谱光纤光源的平均波长稳定性达到0.3×10-6℃-1.

| Abstract: | To promote the broadband fiber source temperature stability,the mean-wavelength stability of broadband fiber source was analyzed and the dependence between the mean-wavelength and the output optical power was revealed based on the simulation and experiment study on the change of mean-wavelength and output power under different pump optical power.A mean-wavelength control scheme was proposed based on the dependent mathematical model among with mean-wavelength,feedback power and environmental temperature by t... |
