There are 3 types of data used in this paper， I.Data collected from Laser Heterodyne Interferometry System A.Spectral data measured with birefringent-Zeeman dual-frequency Laser Heterodyne Interferometry System with the ultrasonic transducer placed 4 cm directly above the laser. II.Data collected from Laser Self-Mixing Interference System A.The ultrasound transducer is 4cm directly above the laser and the signal generator outputs a 10Vpp sinusoidal signal with different frequencies (100kHz-900kHz) . This database is named as “Spectral data h4 output frequency 100to900(50)400to600(20)460to540(10)” B.The ultrasound transducer is 4cm above the laser, and the signal generator outputs a 500kHz, 10Vpp sinusoidal signal, changing the ultrasound transducer in parallel relative to the laser at different positions. This database is named as “Spectral data h4 position” C.The ultrasound transducer is directly above the laser, the signal generator outputs a 500Khz, 10Vpp sinusoidal signal, while the position of the ultrasound transducer relative to the laser is vertically varied (4cm-1cm). This database is named as “Spectral data h4-h1” D.The ultrasonic transducer is 4 cm directly above the laser, and the signal generator outputs a 500 kHz, 10 Vpp sinusoidal signal, with spectral data measured using the Laser Self-Mixing Interference System. E.The ultrasound transducer is 4cm directly above the laser and the signal generator outputs a 500kHz, 10Vpp rectangular wave signal, a sawtooth wave (100) signal. This database is named as “Waveform Data” III.Data collected from Birefringence-Zeeman Dual Frequency Laser Cavity Length Measurement A.Frequency domain signal of Birefringence-Zeeman Dual Frequency Laser. Description of data use： Data II.A.B.C can be used to determine, under self-mixing interference conditions, the relationship between the number of peaks in the measured frequency domain and the independent variable, as well as the relationship between the amplitude of the sub-peaks and the independent variable. This relationship is described in detail in the Discussion section of the paper. Data I.A and Data II.D can be used to compare the measurement results of two methods: laser heterodyne interference and laser self-mixing interference. These are described in detail in the Experiments section of the paper. Data II.E can be observed for the ultrasonic modulation results corresponding to different waveforms generated by the ultrasonic transducer in the time domain. This relationship is described in detail in the Discussion section of the paper. Data III.A can be used to measure the cavity length of the resonator.本文共使用三类实验数据： 一、激光外差干涉系统（Laser Heterodyne Interferometry System）采集的数据 A. 采用双折射-塞曼双频激光外差干涉系统（birefringent-Zeeman dual-frequency Laser Heterodyne Interferometry System）采集的光谱数据，实验中将超声换能器（ultrasonic transducer）置于激光正上方4 cm处。 二、激光自混合干涉系统（Laser Self-Mixing Interference System）采集的数据 A. 超声换能器位于激光正上方4 cm处，信号发生器（signal generator）输出不同频率（100 kHz~900 kHz）的10 Vpp正弦信号。该数据集命名为"Spectral data h4 output frequency 100to900(50)400to600(20)460to540(10)" B. 超声换能器位于激光正上方4 cm处，信号发生器输出500 kHz、10 Vpp的正弦信号，沿平行于激光的方向改变超声换能器的相对位置。该数据集命名为"Spectral data h4 position" C. 超声换能器位于激光正上方，信号发生器输出500 kHz、10 Vpp的正弦信号，沿垂直方向改变超声换能器与激光的相对位置（4 cm~1 cm）。该数据集命名为"Spectral data h4-h1" D. 超声换能器位于激光正上方4 cm处，信号发生器输出500 kHz、10 Vpp的正弦信号，采用激光自混合干涉系统采集光谱数据。 E. 超声换能器位于激光正上方4 cm处，信号发生器输出500 kHz、10 Vpp的矩形波信号与锯齿波（100）信号。该数据集命名为"Waveform Data" 三、双折射-塞曼双频激光腔长测量数据 A. 双折射-塞曼双频激光的频域信号。 数据用途说明： 数据集II.A、II.B、II.C可用于探究自混合干涉条件下，测量频域中的峰值数量、次峰幅值与自变量之间的关系，该关系详见本文讨论部分。 数据集I.A与II.D可用于对比激光外差干涉与激光自混合干涉两种测量方法的结果，该对比详见本文实验部分。 数据集II.E可用于观测超声换能器输出不同波形时的时域超声调制结果，该现象详见本文讨论部分。 数据集III.A可用于测量谐振腔的腔长。
