Based on our previous setup, a signal differential module is introduced to reduce the noise rising from the fluctuation of the laser power to improve the quality of the experimental interferogram.
并在原实验装置的基础上，利用信号差分方法减少了光强波动对实验干涉谱图的影响，改善了信噪比。
It is also shown that many factors, such as spontaneous emission noise and feedback parameter, may influence power fluctuation larger than previously expected.
研究进一步表明，很多因素如自发噪声和反馈因子等，都会对半导体激光器的功率输出产生影响，并且此影响要大于原先预期。
